My family is of Mexican descent. We would often go to Mexico when we were kids and we'd spend New Year's with the extended family (non-JWs). We popped fireworks, ate delicious food, the adults drank beer. The only thing we weren't allowed to do was to go around hugging everyone at midnight and saying "Happy New Year." Somehow this was okay.
On the flip side, I once found myself as an adult on vacation during Thanksgiving with a witness friend. Most restaurants were closed. We ended up going to a local place that offered a buffet and he about blew a gasket when he saw I had put some turkey on my plate. In his mind eating turkey on Thanksgiving was the same as celebrating it. Glad I don't have to deal with that nonsense anymore.
