I dread getting into what I call "Non-stick pan" conversations.
I remember being stuck with a group of, non-working out side the home and proud of it, wives and vainly trying to remember what make my fridge, washing machine and cooker were in order to keep the conversation going. I am sure they had me down as a complete dunce.
Another time, I had always wanted to go to Blackpool but DH didn't want to go, so I went on a coach alone. I was sat next to a man who was over twenty years older than me and having stupidly, told him I was a retired nurse, he followed me around for the rest of the holiday so that he could tell me about all the various illnesses he and his family had ever suffered. As well as having had measles three times in childhood, he had various sordid problems with his dangly bits and liked to discuss them over meals as we were sat at the same table. The final straw was when the waitress asked us how long we had been married. (my DH is younger than I am)
