I don't think people realize what they say really hurt other people's feelings. Even if the person dosen't show they are upset means nothing. I have been in that position where i was made fun of DAILY like most kids. I didn't have the best looking teeth and people would call me different names. It still hurts to this day when i even hear the word teeth. People always need to be aware of other people's feelings. Don't go and make fun of someone for any reason, because you never know what the are feeling. "Treat others the way you want to be treated" (Quote is not mine).
