Why is it that kids hate to sleep and adults love to sleep?

Little miss Rose E is getting too smart for her britches! Every night she now has to sleep with her stuffed "Chevy" dog. Anyway, just about every night we end-up making a mad dash around the house in search of this dog so she will go to sleep. So two nights ago, before the bedtime routine, I found the dog and we headed-up the steps and while I was getting her pajamas out of her drawer the little stinker hid her dog. Then of course the whole family searched and searched for the dog (he sometimes is found in strange places such as the hamper)asking Rose E what she did with it, no luck. Meanwhile this put an extra hour into our routine and I had to convince her to sleep with something else. So the next day I come home from work and the first thing she tells me is "I put Chevy under your bed" and sure enough there it was. Oh what she won't do for some extra time before bedtime! And speaking of bedtime, now when we get her out of her bed in the morning she says in her chipper voice "you find me!" It never fails to put a smile on my face.
Walter's newest obsession is playing a "train game" on the computer. Anyway, it is a neat game where it is like he is driving a real train through realistic terrain and he earns time to play it almost everyday for a short time, so last night before he went to bed I promised that if he slept good he could play it in the morning. So at 1:30 a.m we found him in the hallway ready to play his game. Thank goodness we where able to talk him into going back to bed!
