Fred was tired because he did not relax. It was not sex! I had to concoct a story that because I had been on the contraceptive pill for so many years, I had to take a break. And what do I find a day later when putting Freds washing away that wasn't there before : condoms.
He genuinely used to say: I can sleep when I am dead. He really adopted that philosophy. He thought it was funny that his work mate thought he was so pasty and tired because I couldn't get enough of him and kept him awake or disturbed his sleep . I hope you corrected him I asked. And he just said nothing. Got up and said he had to clean the fish tank.
