In the Jeans

I have one pair of jeans where the fly will work itself open while I wear them. I try not to wear these jeans, but sometimes they're the only clean ones I have. And I don't mean clean as in they-just-came-out-of-the-dryer clean," I mean clean in the sense that they're my only jeans that don't have spaghetti sauce and/or whiskey spilled all over the leg. When I wear them, I have to check every time I stand up or every block that I walk to see if my fly is still up. To the casual observer it probably looks like I've developed an unfortunate tick. And maybe I will develop that tick. Especially if I don't do laundry and need to wear them all week.
