Any advice?

I have to admit I met a hard to handle student today, and its a girl somemore. Girls are somewhat harder to handle and this one was tough cos she refused to even look at me when I was talking to her nicely. I hope she is not going to be defiant when I take over 1 lesson for Maths cos I really don't want to punish her or anything cos I think this is a small matter too. But apparently she's taking it hard and making obvious signs like ignoring me when I tried to talk to her and not greeting me at the end of the lesson. I soon came to realised that she is not like the rest of the students from her strong reaction when she went back straight to complain to her friend. Oh well, young girls.
