I can remember after we got washed up and dressed for bed we would all gather around and watch Little House on the Prairie, The Waltons, Starsky and Hutch, Barretta and Gunsmoke. (the later three being dads favorites)
We would get a cup of ice cream too.
If there was nothing on (and in those days that was often) we would play games. We were all quite competative and card games were our favorite. We still play canasta and poker often with our extended families. (ps - there were 5 of us kids so game nights were very loud and very fun.)
