Usually Calvin goes to bed pretty easily. Last night he was a bit overtired though and Dave took him to visit the neighbors after dinner, which wound him up. Anyways, I read to him and turned off his light around 7 (he'd been up since 6 a.m. with no nap). I figured he would pass right out since he was so tired, but no such luck. I heard him wandering the hallway multiple times. When I walked by his room I saw that he had turned on his overhead light and was laying on his floor, looking at books. Well, I don't really mind him staying in his room and reading, so I left him alone and went downstairs. Dave and I soon heard "wandering" again and told him to get back in bed. The highlight of the night, though, was when a little "robot" voice piped from the top of the stairs "I - am - a - robot. I - am - still - awake. And - I - am - hungry." Dave and I took one look at each other and burst out laughing. We were so amused we brought him a snack - a plain piece of bread that he had to eat in his bed. I guess a hungry stomach was keeping him up because after that he went right to sleep!
