You should have been home

A few years ago me and a buddy were going to catch some wind on the scooters.  I told him what time I'd be there and he said cool.  Well he wasn't home when I got there at the time I told him.  His wife said he was out back finishing laying the re-rod for the new pad.  I went around back and his scooter was gone.  I waited and finished what beer he had in the garage fridge.  After another half hour wait I got bored, so here's what he came home to.
