This is a funny thread.
I was invited to be part of a regular cards night held monthly in rotation at players' homes. Before the first one, I was pretty stressed about what contribution I should make-- more than just a great bottle of wine, something to take. I finally decided on a spread of some really good cheese and a French baguette-- struck me as appropriately hoity-toity for a bunch of SF gay yuppies playing Hearts. I showed up to find out that was totally "over dressed"-- the standing order for cards night was pizza and beer. I totally miscalled it. Still surprises me when I think about it!
