My Singaporean SiL (20 years younger than me) firmly believes that it’s not a ‘proper’ meal if it’s not cooked.
It was many decades ago, but I still remember queueing at some fairly cheap eatery for lunch, with an elderly couple next to me in the queue. There was cold food as well as hot. The old chap just wanted a sandwich, but his wife wasn’t having it! ‘That’s not a PROPER DINNER! You’ve got to have a PROPER DINNER!’
‘But I only want a sandwich!’
‘No, you’ve got to have a PROPER DINNER!’
Poor old bloke! But maybe his Mrs had been brought up like an aunt of dh, who I swear thought you’d sicken and die if you didn’t have Proper Meals, absolutely on the dot, every day.
