Are Sunday dinners a thing of the past?

As a kid, it was always Sunday Lunch at 1 before we were packed off to Sunday School. When we came out of chapel we walked about half a mile to buy a brick of icecream ( vanilla, strawberry and three colours if they had it in stock) and walked home with it wrapped in white paper (we didn't have a fridge or freezer so most things were bought when needed). Aunt, Uncle and cousins would arrive for High Tea (jelly, trifle, that sort of stuff) and we'd play Newmarket, using the same bowl of pennies that came out every Sunday.
Once married & working, the weekends were the only days to catch up on housework, gardening and days out, so Sunday dinner was an evening meal with enough leftover to last a couple of days without needing much cooking.
Sunday is just another day now and I prefer to eat in the evening. Tonight was tuna and sweetcorn pasta - not exactly traditional Sunday fodder.

Gosh - your childhood sounds remarkably similar to mine . I haven’t played Newmarket for years, (used to love it). nowadays we play Uno. Our ice cream was on a stick called Canada Bars, and we ate them on the walk home.
