Pam, when my Dad lived with me (for 7 years before his death at 92) the only swear word he ever said was Sh__, and he said it under his breath. Well, Oliver, my African grey would also say it in my father's voice, but also under his breath. So I would say to him - that is not very nice, so then he would say Oh sh__ - oh that is not very nice. He still talks to me in my Dad's voice - kind of a nice reminder.
