I was born in the late 50s, so I was a young kid in the 60s, teen in the 70s. Another post mentioned families eating together, as did ours. We only had one car (without air-conditioning) and for a while, one bathroom. If the weather was nice, we were outside, playing with neighbor kids and riding bikes (usually hand-me-downs from older cousins). My mother made remarks every evening about how dirty we got while playing outside. Our family "vacations" were spent visiting my mother's sisters and their families in Niagara Falls, NY. Most of my classmates had at least 2 siblings; most had 3 or 4, some had 5 or more. Most of my elementary school (public) classes had more than 30 students. We walked to and from school. Potato chips and coke were a treat that we had in the evening when we stayed up "late" on Friday nights. Our milk and other dairy products were delivered (Twin Pines). The milk was in glass bottles and we gave the empty bottles back. Everyone's house had a "milk chute". I remember my younger sister shimmying through one because we forgot our key.
Children's car seats (if you even had one) were metal frames w/canvas seats (no seat belts) and hooked over the car's FRONT seat.
Anyone else have only three pairs of shoes: church shoes, school schools and play shoes. And they would rotate as such, usually by the time shoes became play shoes they really did not fit anymore.
We didn't have a "milk chute", just an aluminum, insulated box that stood outside the back door.
Remember the cream pushing the cardboard cap out the top of the bottle if it was delivered in freezing weather? Sometimes the pillar was 2 inches high out of the top of the bottle . Then they moved to crimped foil tops .
