Question about adding someone on Facebook?

[Cherry]

on twitter, I don't mind talking to people I don't know because I don't put up ANY personal information about me or any pictures of me, although If someone asks me where I live, I'll tell them (Southern California) and recently one of my twitter friends asked where I live, but it was in a DM so I told her more specifically, San Diego, figuring it's not like she'll see my picture or anything so I was fine with that. She lives in Italy and I can tell she doesn't have very good English but uses a translator for help. anyway, she gave me her Facebook so I could add her.... do you think I should?? although I have no problem talking to anyone on twitter, my Facebook has always been more private. I'm only friends with people who go to my school or I for sure know personally. She will be able to see all my pictures I've been tagged, and other people in my pictures such as my family and my friends. On Facebook, I don't put my high school, but most of my friends do, so she could probably figure out my school if she wanted to. Am i over thinking this or should I add her? I love talking to her on twitter, and will happily add her as a Facebook friend, but I just want to know what I am doing first. What do you guys think?
