Why was she acting like this?

So I was really close friends with this one girl, then we got into this huge fight (this happened last year). We are friends again now since the beginning of this school year. Not close, but we're okay. So I was in class with her (it was the 3rd day of the semester) and I was trying to get her to talk by asking questions and kept being random like I usually am (I have a tendancy tot alk about useless things really fast and ramble on) and she kept saying "why are you telling me this" and "stop asking me all of these questions." Lol I felt really dejected, plus I had a really bad day. I mean maybe she was tired and all and just wanted me to shutup, but I mean is this even the way of doing this? Should I just not talk at all tomorrow? I really don't want to come off as annoying..
