write them a letter to let them know why you absolutely CANNOT serve. They should let you off the hook.
I'm actually jealous. I've always wanted to serve on a jury. I think it would be fascinating.
I got one of these in the spring after just having Jewels. I was so excited about it (too many Grisham books, I'm sure) and had my mom come up from Bloomington the night before to watch the girls. There's a number to call the night before. Glad I did; they'd canceled it. I was so bummed!
