One thing I've enjoyed at ASU is that it consistently reminds that it's impossible to know what anyone is like--based solely on their appearance. For example--in one of my classes there is this girl who seems very intense! First she's very tall--not that I have anything against tall people, but when you grace the world at all of 5'2 1/2" there are a lot of tall people and they can be pretty intense. Besides being very tall, she has quite a few tattoos and a lot of piercings--not just piercings but piercings that make me hurt when I look at her because I can't imagine that they didn't really hurt when she got them! Despite that she's really funny! I've come to really enjoy our pre-class Harry Potter discussions. So not only is she an HP fan, she doesn't drink--at all. She said once that she doesn't do any of that--drinking or drugs--she just doesn't want to do that to her body.
I love being reminded that people are unique, you can't judge them based on what you see--except, of course, when it comes to their shoes!
