When was the last time you were surprised to learn that not all traditions are the same as the ones you're familiar with?

Obviously this was prompted by my funeral procession question, so that would be my answer. But I remember going to Rick’s family for Thanksgiving dinner the first time and found it really odd that it was their tradition to always have chicken and noodles, which they’d put on their mashed potatoes in place of gravy, along with the more widely traditional food.
As a kid I’d visit friends and be surprised at the way they did things.
