Memories of Sleep

Liam is 2. He's not even 3 feet tall yet. How is it that when he ends up in bed with us in the middle of the night after a nightmare he magically morphs into a 6'5 NBA point guard? And what's with the rhythmic gymnastics? He wasn't even awake. Big goofy smile on his face but totally asleep. Oh well, that's what a venti americano was invented for.
