How to deal with a dramatic friend?

I really care about this girl, but sometimes she can be really dramatic and that is definitely not my cup of tea. Is there any certain way I could maybe go about dealing with her sometimes dramatic moments while not getting annoyed. I really do like her and we've become really close friends but those small moments really tend to get me. I don't want to end the friendship or anything like that but I need a way to deal with those small moments when they happen.
