A little bit creepy

So Rey's asleep at one end of the house (working 7am-3pm tomorrow), with Dog-Or snuggled up beside her. I'm still up, and eventually I remember that I was going to do some washing up, so I head out to the kitchen. First I need to clear the rack, so I do that, then I wash various things up. All the time I'm the only thing stirring in the house.

After about five minutes of this I notice an old sandwich that Rey left out to defrost for Dog-Or (we discovered all sorts of ancient treasures while cleaning out the freezer yesterday). I move towards it, I just *touch* the plastic wrap... and instantly there's a cocker spaniel standing right behind me looking hopeful.

How does he do it?
