Would I rather be shopping?

Took my wife to sainsburys, while she was shopping I took the children to the little park. 5 laps in 23.19. Its so boring running round in circles. I changed direction a few times but to be honest it was because there was this dog with only two legs and a sort of wheel attachment at the back instead of hind legs, and no word of a lie I'm sure it could go quicker than I can jog. The kids couldn't work out why I was avoiding it, I told them I didn't want it getting in my way. Had to sit in the car for at least an hour waiting for her to finish shopping - getting cold and feeling cramp in my calfs, while the children insisted in listening to music loud enough to burst eardrums. Lessons learnt?
