Tilly wails until she can see us if she gets hungry
Archie, bless his cotton socks, gets lost in a small 6 room house and "forgets" how to open doors he'd been through only that morning. He then calls us until we rescue him and carry him down the stairs.
Tilly has us all so well trained. She doesn't like Archie as much as she used to but if she can't see him she climbs on top of the cupboard and Screams until he wakes up from his peaceful nap and hurries downstairs.
Of course, cos she's so high up he can't see her, and she's shut up by then so he just sits on the stairs looking baffled.
