My body gets all hyper and excited
Me: What time did you get up today? (Saturday)
The Boy: 6 am
Me: Wow. Why do you get up so early on Saturday, but during the week I can hardly get you out of bed at 7:15?
The Boy: During the week, the bed is so comfortable I just want to stay in it. But on Saturday and Sunday, my body gets all hyper and excited to get up and play video games.
Me: Ah, yes. That makes sense. :/
