Disappearing

The scene: my living room. I sit at the computer. My wife is on the couch. I'm on my lunch break from work. Solving rook problems. I solve one and go onto the next one. I eat a little. I keep solving. I hear a noise, muffled at first. It sounds distant. It's a woman's voice. "Are you watching your time?" I look at the statistics. I have about 12 more problems to go. The clock says its time to head back to work...but I don't want to quit solving. Where have I been? Where has the time gone? Disappearing.
