She gave away all of her blood.

I went on a business trip this weekend. When I got back, it was halfway through church, so I slipped into the pew next to Keith. He whispered, "I'm so glad you came back and you didn't die!" Then, when the kids joined us after their class, LittleBug said, "I'm glad you're not dead."

It turns out, over the weekend, Bug asked Keith, "Is Mommy dead?" No! Why would you say that? "Because she gave all of her blood." Oh. Oh, no, honey, we are always making new blood and she only donated a little bit. 

I guess I won't be taking any more road trips days after a blood donation ever again.
