Is she angry? FB chat or in person?

[Sarah]

you are a boy, if you could just walk to her and talk you would have done it by now. now that you feel different with this girl then starting a chat in fb is perfect since you can have something to talk about when you are going to approach her the next day. you had to take this excuse away from you and talk to her after you chat. right now if you pass by her and don't talk it is not that bad but when you chat you are gonna have to talk when you see her. you can always start up with some thing you both have in common which is the school in your case. talk to her about funny things. like if in your school you have a wired teacher or some one who is always angry .... you are a senior so you can just give her tips and tell her about your freshmen year and the funny stuff happened. did anyone teased any teacher or ....
im sure you can find a nice topic to talk about. don't show like you are too small and also don't show you are shallow. be yourself and it will come naturally
