I hear you about not taking for granted anything one has or never had. But I have to pleasantly interject on the ketchup (catsup?) sandwich thing.
I remember that I was 8 when I heard my mother in Buenos Aires tell our housekeeper to go to the corner store to buy catsup. She spelled it out. And of course I was 8 when I first tried and fell in love with catsup.
Ketchup is always in my fridge and I even dunk very good imported Gruyere slices in it! Don’t deprecate (and with no wish to offend you) our marvelous ketchup.
