Last weekend I phoned a local florists
and asked them to send some flowers to a nearby friend.
The friend lives in a relatively small cul de sac. The florist obviously asked the address for them to be delivered to. I advised they lived at No 12.
She then went on asking all sorts of questions about how she could find the house once in the street, ie what side of the road etc. She then asked questions about what would make the house recognisable to her, ie what colour front door.
I had to bite my lip but really wanted to respond "the fact that is has the number 12 on the door"!
