I hope the memorial service was good and had some positive aspects. It isn't all about doom and gloom. There was a lot of living in your grandmother's (and my grandfather's) life. Focus on the good parts. I know my grandfather would.
Get some rest - that's a lot of driving. And do something fun for yourself.
I got in a pretty good zinger with W yesterday - not a mean comment. It just sort of happened. It's in my thread.
