I come. You go.
I'm nice. You're grouchy.
I'm up. You're down.
I'm big. You're little.
I'm in. You're out.
I'm on. You're off.
I sit. You stand.
You're slow. I'm fast.
I'm tall. You're short.
I have a lot. You have none.
I'm dry. You're wet.
You're dirty. I'm clean.
I'm black. You're white.
I'm awake. They're asleep!
