Stupid.

" What's the meaning of a cladogram??"  You sit there and think, everyone else knows the answer and you don't. "I don't know." sends your self-esteem in a downward spiral.  How do you think it feels when someone calls you stupid but you know that they're kidding and even though you know they're kidding it still hurts.  It still makes you feel like you're a complete idiot.  You sit in class and when called all you can do is say "I don't know" and laugh just so people see that you don't care.  But you do.  It tears me up inside to see friends feel that way and I even have the occasional feeling.  All I can do is tell them/myself that I'm okay with what you/I know and what you/I don't know. Don't let some silly little question that most likely will never be used again interfere in your lifestyle.
