If I have really STRONG impressions of people, then that is always right. It's when I hae a weaker impression that I can be wrong (usually negatively... I tend to think they're ok people, but then they sometimes wind up stabbing me in the back.)
I have two stories about times I've had a very, very strong impression of people.
The first was a guy I took an immediate dislike to, very strong dislike. He was also both gay and a "little person", so I was afraid I was being prejudiced! I had dealt just fine with gays in the past though, so I didn't think that was it, and I'd had very little experience with little people. I was STILL afraid that I was being prejudiced about this guy. Then a couple months later I found out that he had been imprisoned for raping a 12 year old boy. It was the fact that he was a child molester that I was picking up on in my first impression, NOT anything to do with being gay or a little person!
The second was a guy who I practically fell in love with at first sight. I later found out that he shared my political views, which was VERY rare where I come from! And that he shared my weird eclectic tastes in music, scientific interests, didn't want kids, liked cats, and even liked to cook! (I like a guy who likes to cook because I hate to cook! Someone has to prepare the meals, right? :biggrin1
. Unfortunately for me, he was already happily married to someone else. I hadn't met someone who I had so much in common with before, and haven't met one since. (And I even heard hearsay that he was very well endowed, too! Talk about adding insult to injury for me!)
