I just added a girl on fb. she accepted the next day. we have a few mutual friends. it's been a few days since she accepted but I haven't messaged her. how is this for a non-generic opener:

"You should be an actress. I really can't tell how old you are haha. You could pass for anywhere from 21-35"

(that's not actually true, I just figured that comment would elicit both good/bad emotions)
What do you guys think?
