My FI and I are attending a the wedding of our two friends this weekend, and just got a FB message from the bride asking we could help serve cake at the wedding reception. And I'm not sure how to feel about this. On one hand I'm always willing to pitch in and help if I see it is needed. However we are traveling a good 5 hours each way for this wedding, getting a hotel, sent then a darn nice gift already,... I just don't know! Is there an honor to this I am missing?
