Your firneds Password

What do you think about knowing your friends' passwords -- school login, myspace, email, etc? Would you share your information with anyone else? What are the risks involved? I dont know my firends password. My firend Breann knows mine. I don't like people my friends password that wronge. They can change stuff on yor profie. If they do something wronge on scool progame they can get you in troble. If I knew what it was I whoudn't share it with no one.
