We went outside and played on the neighbors' swings for a while. When he tired of that, Matthew took me over to where Rachel had hung a whiffle ball from our porch for him to swing at. "Dada hit ball!" Uh, okay. I'll hit the ball. Where's the bat? "Oh! Bat!" and he fetched the bat from its bin. Then he started running up the stairs to the porch.
Puzzled, I tapped the ball once, and twice. Then it started rising up towards the porch floor! Hey! Where's the ball going? Two-year-old chuckles ensued and Matthew grinned down at me from where he was pulling the ball up.
We played this for a while. He'd let me hit the ball a couple times, then raise it out of reach while I pretended to be puzzled and dismayed. He was enormously amused.
