I couldn't find you!

This afternoon I was feeling a little tired and decided to lay down with Reese during her nap. I was totally falling asleep while she arranged and rearranged the covers, played with the pillows, talked, sang and various other things to keep from falling asleep. Finally, she was out and I woke up from a 20 minute cat nap. I snuck out of her room and downstairs to get some stuff done. About 2 hours later she awoke and started bawling. She made her way down the stairs and exclaimed, "Mommy, I couldn't find you in the bed! I didn't know you were downstairs."
