Back at mom's place and even when it used to be mom and dad's place it was the exact same thing. No cooking on sunday evening!
Indeed, it's a very common thing, I believe.
One thing I have noticed is that papa tries really hard with his cooking, but he is not as good as my mother. However, he's improved loads since they divorced, which is no surprise.
Here Sunday lunch is the important meal. Dinner is leftovers or toast
That is exactly what we do here. Ever we go out for Subday lunch or have a traditional Sunday roast at home, which is always a highlight of the week.
