Hehe - I know where they ended up before morning!
One time, nephew of about 4 years was over. During the reading he interupted me stating that he really was interested in hearing the story, but, he wanted to know if I had ever noticed how dark the kitchen was when the lights were out.
Well, turning on the stove light solved that problem. Then he said he was too sleepy and thought it would be a good thing to hear the rest of the story in the morning. He finally dropped off after I let him 'examine' an unloaded firearm, a dummy hand-grenade and a dull pair of antique swords, in his bed, for the rest of the night.
Kids are great.
