Well often I might see somebody waving out by the gate frantically trying to get in where he's put one of his different size padlocks round the gate, the back gate and the front gate, and often if we need to feed the cat he's padlocked all the different padlocks round the kitchen cupboards erm we've been unable to get the cat food out, so we've had to go off in the car and bring him back from a friend because he's the only one who knows which key goes with which padlock to undo all the cupboards.
