Yesterday our washer stopped spinning. Not wanting our laundry to back up before we have it fixed, I decided I'd rather go to the laundromat. So, I asked Maya & Isaac (the only money-motivated children in this house) if they had any quarters. Isaac said that he had plenty, so I told him I could trade his quarters for dollars.
So he asks: But how many quarters for a dollar?
I said: Well, how many quarters are in a dollar?
You should have seen his face deflate as he realized I was going to do an even trade.
In true Isaac fashion, he held up 2 fingers and said, disappointingly: Four quarters.
