I think there was much less booze, certainly in the late 60s to late 70s. Beer, a small sherry or two, maybe crack open the advocaat, and the cooking brandy after dinner.
Also, things were more seasonal then; Quality Street really was for Christmas, not life, so it always felt special, and things like twiglets and cheesy footballs weren’t an everyday snack. After Eights and Matchmakers were very sophisticated.
Finally, we just had less stuff in those days, maybe because there was less stuff to have, but still, a new board game was a source of excitement, and something we played together. A lot of gifts these days will be more solitary, particularly personal tech. I also remember when advent calendars had a picture behind the doors and nothing else, and I don’t think they were any the worse for that, it was all about the countdown to Christmas Day.
That’s not to say I don’t enjoy Christmas, I do, it’s just changed in many ways since I was a child.
