I do host thanksgiving for more than 20 usually, we do an all-comers meal, whoever wants to come to eat can. It’s fun and I enjoy it and yep everyone brings something but even so it is expensive for certain. Legitimately thankful that we can do this for everyone. But even when I was younger people coming to Thanksgiving brought something, is that not a usual expectation if you are going to a party? At least bring wine or ice or something.
