If you go to family for holiday meals, do you bring a side?

Growing up, we would often go to my aunt's house for holidays, or we would also host holiday gatherings at our own house. My family was always big on the idea that the host provides everything (main dish, sides, drinks, desserts), and if anyone asked to bring something, they would say everything was covered. My husband's family is the exact opposite. They ask us to bring a dish for every occasion that we get together. They also tell us to bring our own beverages too, because they typically only have water at the house. I understand that it can be a lot of work for the host to provide everything (I've hosted three Thanksgivings now and provided everything), but I'm still getting used to the idea of being asked to bring a dish to every holiday get together. Just curious to hear what others do.
