First impressions really do not last. In my case, it's already tested and proven because almost all my friends are the ones whom I thought I would never get along with.
I remember back in high school, there was this girl and her is Margareth. She's pretty, petite, and quite popular. She's nice but I don't really like her because she looks like a snob and "maarte". When she became my classmate during 2nd year high school, she started talking to me because we're groupmates and then the next thing I know we were always talking and hanging out. Long story short, she became one of my best friends. My impression about her was all wrong. She's not maarte. She really nice, humble, generous, and funny. We got along very well. We have the same taste in music, movies, clothes, and boys. She like my sister already.
I told her about my first impression and with her and how I thought that we would never get along and guess what? That's exactly what she had thought so too.
