I can say I am taking him somewhere - beach, doctor, barber, church and we are driving there and dad keeps saying where are we going. Almost child-like wanting to hear his own voice, We can't tell when he really can't remember or is playing a game. It is very frustrating. I know not to show anger, or be rude etc. But the way he speaks to myself and my sister is at times nasty. Then he'll say I'm only joking. He does not speak to our brothers that way or their partners. Any suggestions on how we can rectify this or at least make it easier to live with.
