Ah. Here he comes. Mr Postman. With a great red satchel full of red envelopes!
Gosh, he's spending rather a lot of time at No 6. I suppose it's their teenage boys. All those lovelorn schoolgirls...
Ah. He's crossed on to our side now. No 5. No 4.
No 3. No 2. No...
Hang on! What's going on? He's turned on his heel and is walking back down the street, his satchel slung nonchalantly - not to mention emptily - over his shoulder!
Maybe he's gone to fetch his trolley. The one with all the really heavy things in it.
