Well, you know that roof you fixed the other summer? It’s begun to leak again. Could you come round to sort it out?
You don’t work there any more? Firm taken over? Oh. Could you let me have their contact details?
You could but they only do demolition now? Oh dear.
Well can’t you come round and take a look anyway?
Oh you’ve left the district. So what are you doing?
Oh, a job in London, selling papers, for the Russians! Nice little earner you say.
That sounds nice, but what about my roof?!
