I heard them upstairs talking with a door between them. Technically Nathan was screaming but Ethan was talking.
E: Hey, Buddy. It's time to take a nap.
E: Buddy. Even I am going to take a nap today.
E: Nate, do you know what you can do?
There is a pause in the wailing.
E: Do you know that you can do? If you don't want to sleep (dropping his voice), you could just play in your room. Sometimes that's what I do. When Mom tells me to go to sleep but I don't want to, I just play. You could do that too.
Bless his heart, the wailing started up again. I guess Nathan decided that he preferred his freedom to anarchy. But at least now he knows his options for next time. I guess that is why little brothers have big brothers, right?
