At first, all her friends ARE mad, until they figure out that it was YOU, not her, that sent the mean e-mail. Now they're all mad at YOU, even though you tell them it was a joke. You are made a pariah of the schoolyard. Everyone hates you. You consider jumping into a hive of deadly scorpions. Since you logged on using this girl's account without her permission, you invaded her privacy and probably broke the rules of your school, not to mention America. You could be suspended from school and your computer privileges could be taken away. It's not worth the risk. Rather, it wasn't worth the risk, but you did it anyway because you're a sucker. Pathetic. You are scum.

Think about it:

Is it okay to pretend to be someone else when you're using a computer? How would you feel if you found out that the person you've communicating with over the Internet was not a kid, but an adult pretending to be a kid? Would that be messed up or what?
