I'm not going to participate in my husbands family's white elephant
Why would you refuse to participate in something so fun?
Because I feel like it's all fucking stupid.
Regardless of how you feel about the event, it is expected of you to participate in family events. In the future, you may want to consider that they participate in your events.
Nah, I don't have to.
You do not have to, but I think that it might be a good idea to at least try. You should make sure that you participate in family events in the future.
