yeah..I think it's all based on the impression you get of somebody from the first couple times you meet them...whether impression is based on how they really are, or not, it usually sticks & determines whether you want to get any closer to them
see the first time i met her (about a year ago) i got such a bad impression. then when i met her again a few months ago i didn't realize she was the same person and the way she acted that day made me like her.
