Um, well, I'm sure if your Aunt were a famous person who was in the limelight for quite a few years you, or if you were an older/more active member of the form, you could have made a thread about her death (sorry for your loss, by the way. Loosing family sucks).
However, she is not, so don't whine about that to us.
As for Heath Ledger --I was in the car on my way to work when I heard about it, and was like, "Whaaaaat?" switched to another station, heard it again, and basically drove to work in a bit of a shock. I mean, I've seen a pretty fair share of his movies, and I really liked him (not because he was a hottie, which was a plus, but because I really liked the characters he's played --10 Things I Hate About You is one of my favorite movies) as an actor. He really was just starting to develop a serious acting credit, and this is kind of shocking.
He's not that much older then me, and he's dead... There are actors way older then him that I am afraid of dying soon, and this just makes it all the more "in your face" that everyone's gonna go sometime. (On another, sort of similar note: I am now even more scared that Alan Rickman is gonna die before I get the chance to meet him...eeeeeeeeeeeee)
