Wife: Can you bring me a glass of water ? Me: sure. One hour later ... Wife: What took you so long ? Me: I couldn't fill the glass because there where dishes, and the dishing machine was full, so I had to empty it, then I couldn't find the dishing tables, so I put the kitchen cabinet's in order, but accidentally spilled some flour, so I cleaned the floor and worktop while I where at it. Next day at work: Boss: Can you implement feature X ? Me: Sure ...
