I think there is a fine line between people who have dramatic events happen in their life... and people who create/orchestrate drama.
It's the difference between watching Jersey Shore... and just about any other TV show.
I am always there for my friends if they are in the midst of bad things happening to them. I run for the hills when it becomes apparent that my friend is just creating drama to get attention. I am really bad when I sense that someone just wants my attention... I tend to shut down and disappear into the night.
