I heard my dad swear twice. The first time I was thirteen and he'd collected me at the end of term from boarding school. Someone cut us up coming round the Denham roundabout on the A40. He forgot I was in the car (so he told me later on), opened the window and let out a torrent, lol. He said that you don't spend six years in the army without learning some choice language. The second time was to my stepmother. She had really given him the benefit of her opinion (no doubt he'd breathed wrong or something equally as despicable) and he gave her the benefit of his. Twice in 34 years isn't too bad I don't think. I'm not proud to say that I think mine have heard me come out with it twice in as many minutes on some occasions.
