The scene: I am sitting on the computer in our bedroom, Ari in the hallway and is mysteriously quiet except for a strange clicking sound. Wil is sorting and folding laundry.

Me: What’s he doing?
Wil: Playing with that square thing.
Me: What square thing?
Wil: It’s white and square.
[A pause while I try to determine what he’s talking about]
Me: Is it safe?
