I have, actually i do all the time. I dislike I'd say 75% of the people I encounter almost instantaneously. I used to attempt to move passed this feeling..however over time I found my first instinct regarding a person good or bad was rarely incorrect..in fact I can think of only once ever. As a result.. I trust that instinct and just avoid those I get that feeling with.

Yeah, I am a hermit.

I usually give people I meet on the internet a wide area. The only reason I might instantly dislike someone on the internet is if they write stupid, offensive, or ignorant messages. Even then, I might not actually do anything about it because it could be an online persona. For instance, I used to read the momlogic website, when I had time to surf. There were some posts by people that were anti-children. Now, I don't care if someone doesn't like children, but they would get on and post mean things about hurting other people's kids if they saw them fussing in a store or just generally stupid stuff. Some people would get all riled up. I was annoyed but then thought that the person might be doing it just to make people upset. It goes back to that anonymity thing that the internet provides. That person's posts got alot of hits people other people would flame the person. It's just hard to tell whether what someone writes on the net is true or just for posterity.

So, I do move past the feelings because I have no personal connection to the person. If I continue to visit areas where the person posts, I might avoid his or her posts or I might read them to reconfirm the fact that I dislike the person. However, sometimes a person's posts start out bad and then get better over time, in which case I will most likely change my view and consign the original posts to the forget pile if the person continues to post well.

This is all very vague and hypothetical but suffice to say, since I don't know the person in real life, an instant dislike might be a misreading on my part and only further instances with this person's writing will reveal the truth of the personality.

Many times already.

But, I've learned a lesson. I won't judge them right away because I've been wrong so many times. There are people I know who seem so kind and sound angelic when they speak to you but if you know them well, they are not. They're just wearing masks.

I definitely have. I've often noticed it's because they've done or said something that made me associate them with someone I have actually gotten to know and didn't like. Sometimes they just look like someone I don't like. When that happens, I try to remind myself that it's not at all fair to dislike someone just because they happen to look like someone else, sound like someone else, or merely have a habit that someone else has. In those situations, I really try to see them as themselves, and get to know things about them that help me distinguish them as an individual.

If the person actually does something that is inherently unlikable (says something homophobic, is rude to someone, etc) I have a hard time wanting to give them a second chance. In those situations, I tend to just avoid them, since I figure life is too short to spend with obnoxious people.

I have two situations in my life right now, both online and in real life.

I met a lady who is the mutual friend of two other friends. She moved here from up north, and invited myself and my friend over for dinner a couple of times, and my friend invited her over. She is nice, has never said one thing out of the way to me, but she just has this way of looking at me that makes me uneasy. I've asked my friend not to include me in things that she is attending anymore because of this. I know she has probably noticed that I'm never around when she is, but I don't care. She just gives me the heebie-jeebies.

Online, there was someone I knew who was always rather sarcastic, and could be a little caustic, but was never really intentionally hurtful. I let the ascerbic wit ride until the other day, when they posted something really mean spirited, and potentially hurtful to a certain group of sensitive people. I got angry and responded, but then realized I was so angry that I just needed to cut this person out of my circle of online acquaintances, so I did.

Some things that I don't tolerate, in person or online, and that will turn me against someone in a heartbeat 1) a man who just meets you and immediately wants to talk about sex, or makes sexually inappropriate comments 2) a woman or man with a very nasty mouth 3) anyone who is way too aggressive in public with someone else's Significant Other and 4) drunks who try to touch you inappropriately in public. All these things are matters of respect for others and for self, and I'm big on respect.

Possibly when I was young. But at this point I've learned to start everyone out at 100% and then they can work their own way down to dislike if they so chose. This does not mean I instantly lend money or my car, etc., but I will give you the benefit of the doubt once and then move more cautiously.

For people I met in real life, yes a lot of times, and I usually will be proven right later on. there are a lot of times that I try to get pass my initial dislike or reaction, but again, usually if I instantly dislike the person at first glance, the impression is usually correct. I can count on one hand how many times I was wrong. But if I instantly like some one, I might be proven wrong later. So even if I like someone initially, I could be wrong.

I can't explain how I react that way, I just know. I know that I have a knack of knowing people, and maybe that's why I chose my current profession. To my clients or students I never feel this way, maybe because they're my charge.

For people I meet online, it's trickier because I can't see their body language. I usually don't have spontaneous reaction to people I interact with online, and there are many times that I am proven wrong (I've disliked several people only to discovered they're actually nice) Body language and face expression are something that are missing from online interaction. I;ve been fooled once, when I was in high school, but usually people I meet online are nice and helpful.
