Every celebration seems to have unspoken rules. What's one that always makes you smile or roll your eyes?

A natural way to answer

For me it's the rule that you must never arrive empty-handed. It's never stated, but you just know you'll be quietly judged if you do. I find it funny how something so unspoken can be so firmly enforced.
