Suspicious disappearance

[hearthstone]

So it's another nasty, stinkin' hot day here (yesterday we got the giant fan out of the basement for the first time all summer) and I'm thinking tuna pasta salad for dinner.

So I start the water heating and go to get a couple of boxes of pasta. I discover that while I have four kinds of salad-worthy pasta on the shelves--rotelle, radiatore, penne, and elbow macaroni--I have exactly one box of each. This is very odd because I only ever buy pasta in increments of two.

So I guess I'm mixing (I'm thinking rotelle and elbow macaroni) but mainly I want to know what happened to the rest of my damn pasta!
