My DH, his sister and my MIL were the fastest eaters known to man - they should’ve had racing colours on their knives and forks! You could say they ate to live, had asbestos mouths, but seemed oblivious to any taste or texture. I used to leave half my meal untouched, as I was always very self-conscious of holding them back, as they’d already picked their puddings! Years later going out with DH, I’d ask him to eat slower, but he wanted his food like lava! He’d ask if I didn’t like my choice, should I ask him to help me eat it. I’d say it was fine, delicious even, but that he’d wolfed his down at a ridiculous speed!
Luckily DD2 who I eat with quite a lot, is a very slow eater, enjoys every mouthful too.
