My grandson asked why I always put the cheese grater back in the drawer before I finish grating the cheese.

I told him it's because the grater needs a little break between shreds.

Punchline

He said that doesn't make any sense.

I said, "Neither does grating an entire block in one go — that's just grate expectations."
