Yes I get that years ago everybody worked long hours and Sunday was the only time people could gather together to eat.
But times have changed.
If I get up on a Sunday and it's a really nice day, rather than spend all morning cooking, we will go out for the day.
We'll have the Sunday lunch on another day during the week..
I don't want my whole day to revolve around a meal.
My DM is always horrified ^But You have to have Sunday Lunch!''
'How can you not have Sunday Lunch?
Me Why?
DM ''Because it's Sunday!''
I think she would have a hear attack if I told her that sometimes we live really dangerously and go a whole month without seeing a roast potato 
Before the food police have a go, I cook really healthy meals, and we sit down to eat as a family on a regular basis,
just not always on a Sunday.
Anybody else have older parents who think this way?
