Realities of the Tang Household

My dad and I are big eaters, and we're back at the family home for Christmas. My brother made the following observation about the situation.

"Usually when it's just mom and me, food goes bad and rots. When Anth's home, then there are no leftovers. When dad and Anth are home, then there's no food at all."

It's true. I'm going grocery shopping later today, and we just went yesterday. This is getting kind of ridiculous.
