Many years ago, I drove round to visit a couple I knew at the flats where they lived.
Unfortunately, there was no reply when I rang the bell and so I decided to stand outside for a while on the off chance they'd return in the relatively near future.
After about ten minutes, the door opened and out stepped a little dog followed by one of the best-known faces on British television. I'm not going to name her on this site but, apart from her TV work, I do know she played a role in a film alongside one of Britain's most successful TV comedians.
I explained what I was doing and who I was waiting for and it turned out that she lived in the flat directly above my friends and was on nodding terms with them.
She wandered off with her dog and, upon returning some minutes later, asked me if I'd like to come up to her flat to wait for my friends rather than stand outside in the cold.
Being a sociable sort of person, I accepted her offer.
I'm writing this before the watershed and so I can say only that I didn't see my friends that day, or even that night.
