Growing up, the whole family sat down to dinner, in the dining room, every night. Well, dinner on Sundays was at noon. Mom, Dad and us seven kids.
Breakfast during the school year was staggered as we went to 2 or 3 different schools, with different start times, so we'd trickle down to the kitchen in shifts. During the summer, Dad would leave for work early, but most of us would eat breakfast with Mom in the kitchen. Once you were in high school, you were allowed to sleep in during breakfast during the summer.
Lunch was always eaten together, in the kitchen.
As we grew older and the boys started joining sports teams (there weren't any for girls back in the 60s), they might miss dinner one or two nights a week, but the rest of us all ate together. The four oldest of us had assigned chores--setting the table, clearing the table, doing the dishes and sweeping the floor/taking out the trash. I can remember more than one night when the three oldest boys would be at a game or practice and I had to do all the chores that night, and many more where I had to do the chores for one or two of them. Now, when we have family get-togethers, I sit back and let them do the clean-up. I figure they owe me years of doing their chores.
I remember being taught table manners and how to carry on a conversation while at the dinner table. As well as the boys' burping contests while Mom was out in the kitchen getting dessert.
No TV was allowed, no radio, we couldn't take phone calls during dinner. Sunday dinner was a pain, because of the no TV rule. The boys would all be watching a football game and Mom didn't want to make them miss any of it, so she'd hold the food until half-time. I'd be starving, but I couldn't have a snack, because we were "about to eat." Only with all the time-outs and stuff in sports, those last 3 minutes of a quarter last half an hour.
Oh, and everyone had to wear a shirt at the dinner table. Not really an issue for me, but in the summer the boys tried to wear as little clothing as possible.
