For those who find jja's puzzles too arbitrary, too open, or otherwise frustrating (rather than fun) here is a thread for puzzles that have only one answer which can be guessed from the provided information if you think laterally enough.
Here's one to start.
True story: In the summer of 2007 I had a temporary part-time teaching job. One of the other teachers was a woman whom I befriended. She was also studying, and she spoke of the difficulties of juggling work and studies when one is a single mother.
One afternoon I visited her at her mother's house, where she was staying with her two year old son. Her mother looked after her son when she was working. (I did not meet the son.)
While I was there, the phone rang. It was the young woman's husband. Hearing half the telephone conversation, it was obvious that the two were very much in love - and the husband was the father of her son.
She had not lied to me about being a single mother, yet she was also happily married. How could this be?
That same summer, I had been teaching at Havant College, delivering mathematics lessons in the evenings for adults who had not gained a mathematics qualification when they were at school. When the term ended, there was no more teaching work, so I had to sign on at the Benefits office. I was interviewed by a woman who explained how Benefit worked. She and I had never met before, but she had a photograph of me on her desk. Why?
I'm on holiday so I might not be able to check this thread every day.
