Bobby at the window

As the days get warmer, the dog down the road takes up his position at the window, watching passers-by. Say 'Bonjour, Bobby!' and, freakily, a disembodied voice from inside the room says 'Bonjour' back. Great for scaring small children. Oh, and if the windows are closed, Bobby's often kept in the bathroom, from where he will bark furiously as you pass by. That'll make you jump each time...
