Why does my Aunty give me dirty looks?

I don't know what her problem is but every time i'm at a family gathering I see my Aunty give me dirty looks. I actually don't like her and don't know why she gives me them.
What could be the reason?
It makes me sad that she can't come and talk about these things with me? Like we are both adults? What is her problem?
