I picked my daughter up from a sleep over this morning (these should be called stay up all night overs, for truth in advertising purposes :) ) Anyhow - as we walked home, she made a point of telling me how hard it had been to fall asleep after getting such a good night's sleep Friday, and how she wasn't really tired. I sent her up to change, and found her fast asleep a few minutes later, after I wondered why things were so quiet. Not tired my foot :)
