When I was a boy we were taught to thank our mothers for everything they did for us, including cooking meals.
As an old and frail man, I find still having the ability to cook for my kids is one of my greatest pleasures. I have to believe many generations of Moms feel as I do.
No need for thanks. It was my pleasure. I do not know how much longer I will be able to do it, but it would be fine with me if the last thing I did was to cook a meal for my family.
