why cant i sleep?

I'm tired, ive been up since 5:30 or so. I just cant sleep. I'll go try again, have to get up to get Munchkin ready for school in the morning. There are only 12 days of the school year left, (not counting weekends,) yay! then I'll have al day with my little buddy. I'm so happy we bought the Friends of the Zoo membership though. We've used it so much in the past month, the expense is more than covered. And, we get into other Zoos for free. They advertise on the card, "Free Tickets to the St. Louis Zoo!" and I laugh...
