How do I convince my mom to let me have a facebook?

[DCK]

Well since you're 13, you can tell your mom that Facebook will automatically hide your information / pictures/ profile etc to people who aren't your friend on Facebook. (That is if you put your real birth year). You can also promise her that you aren't going to add some random person you don't know as a friend, and that when you have a school assignment you can just send a message to their Facebook instead of calling them. Oh yeah you make sure to tell her that you won't be on it every SINGLE day, I'm warning you, Facebook is VERY addicting.

PS: Ask her when she is in a happy mood.

Hope this helps!
