kid logic

The other day, on our way in to Target before lunch:

Me: Now, we're just running in here to get a few school supplies that are on sale. We are NOT buying any food.

Joaquin: Can't we just get one thing?

Me: NO. I have lots of things at home we can eat.

Joaquin: Can't I just get a grilled cheese?

Me: NO. I can make grilled cheese at home.

Joaquin: But, WHY can't we get something?

Me: Because I have all this food at home. Why would I buy it here, if I have it at home?

Joaquin: Well, buy something you don't have.
