Shopping bags

So we get home from the supermarket, I put all the stuff away and put the empty bags in the cupboard and go through to the office to check my email. I hear the sliding glass door open and Ben go outside, I come back through to see what he's doing and he's looking for something on the patio, so I leave him and go back to the office. Next thing I hear him come back inside and hear the cupboard door open. By the time I get back through to the living room the game is in process...
