sad news today

I got a text this morning from my good friend, Vanessa, the one mentioned in a previous post, that her dad died yesterday.  He had routine gall bladder surgery last week, and was relatively young (around the age of my parents) and healthy, and he just died yesterday!  I can't believe this really happened.  Vanessa has a really close family, and over the years of knowing her, I've known her family to be incredibly warm and inviting and just really fun people.  I am so sad about this, and don't quite know what to say.
