Married with 3 teenagers (well, almost, 15,14,12). I have to buy in bulk each week just to keep us fed.

Funny story from a few years back. My wife's brother was visiting, he's a single guy and doesn't drink skim milk (our normal milk). We go to the store and buy him a 1/2 gallon. He looks at the expiration date on the milk, it's like in 2 weeks...

Art: "Geez, I don't understand why they even sell milk in more than 1/2 gallon sizes, no one will ever drink it before it goes bad."

Me: "Art, we've got 3 kids, we'll go through a 1/2 gallon at dinner tonight."
