I believe it’s just a lighthearted, fun discussion. Everybody has things they especially like or dislike.
I’m not a picky eater at all, but I strongly dislike Brussels sprouts and mac & cheese.
I’ll gladly take the brussel sprouts,and turkey,ham, sweet and mashed potatoes, cranberry, green beans (not casserole) stuffing/dressing,hot buttered rolls, fruit pie with ice cream plus NIG glass of milk.
Brussel sprouts( like almost anything..except cake)...goes well with BACON.
