Proper ice cream is 20 degrees F. It’s too cold to just schlorp it off with your lips. If you can, it’s melted and you’ve missed important texture. That’s why I eat my ice cream with a knife.
Lol, do your partners\parents\siblings complain that you consume too much if you’re sharing something? It’s not our fault they consume things so slowly.
This absolutely has happened to me in the past. I ended up just letting them take the first few “bites” and then I would just destroy the rest in a few actual bites. You’re right though, it is their fault after all!
Chewing prepares your gut for digestion iirc, we didn’t evolve to eat blended foods so the gut isn’t ready for soup, so chewing is probably beneficial?
