FI's best friend is getting married next month. The groom's father is hosting a party at a restaurant for the couple this Saturday. I guess it's not really an engagement party because the couple has been engaged for over a year and a half. It's not a "Jack and Jill" because we received an invitation rather than buying tickets. I don't know if we should bring a gift or not. We will be bringing one to the wedding next month. Anyone have any thoughts?
