People are so different, even among single families. My parents and my sister insist on using a knife to cut a pancake. The fork goes through it like butter, minimum effort, but no! They must use the knife.
My brother and I are similar in that we will eat food cold, even out of the can, like regular losers. No problem. I've eaten hundreds of cans of chilli right out of the can. I actually prefer it that way to heating it. My parents and sister insist on making food so hot it's practically inedible, especially my father. He'll take a plate of cooked food, just served, and stick it the microwave. Then he'll gasp and pant as he eats the lava-temperature food, and if it cools too much while he's eating it, he'll pop it in the microwave again.
But it should be mentioned that I'm basically careless about food, and watching a show like Hell's Kitchen is about as interesting to me as watching paint dry.
