Your teo sons cook well in spite of your NOT teaching them cooking or because of NOT teaching them cooking. Kust kidding. Don't take it as an offence. I have always been feeling that kids both male and female should be taught cooking. In our days we were prohibited to enter the kitchen. "இதெல்லாம் பொம்பளைங்க சமாசாரம்" days are over. I feel the pinch of it now after the demise of my wife
I am sure my two sons cook well - in spite of my not teaching them even the basics till they left for USA. I myself id not know any coking till I got married in 1970.
My elder sister ( older to me by 4 years) used to help my mother in the kitchen. I was busy preparing for my music exams and with dance practice.
I had spent 8 years in the ladies' hostel ( 4 years while studying and 4 years while working in a women's college)
So after getting married, when I first made rava upma to impress my very talented S.I.L,
it turned out to be a porridge. Later on I re-discovered the proportions of water with the stuff being cooked as well as the portions needed for serving an average adult.
No one would give the ratios as they all kept saying "kuthu mathippaa seiven" or " kaaN paarthu seiven".
I am sorry to learn about the sad demise of your wife. Many men take their women for granted when they live and serve silently - looming at the background or becoming a mere shadow of the men folk.
The void or vacuum left behind by them will be felt only the wife is no more!
