What do you think this means?

I am in high school its my first year. I am a female. There is this guy who I just met this year, I still really don't know him all that well. But he seems to be really concerned that I don't talk that much to people in cl when we are allowed. (meaning when ever working or when the teacher is not talking). I believe I talk plenty. Any ideas why he might be pestering me about talking to people?
