Believe me, a no gift party IS an event. Cannot believe for the life of me figure out why some people are so hung up on the idea of bringing a gift. As said earlier in this thread bringing a gift is done to relieve a person's guilt when non in requested. That implies the party is about them when it is not.
Do you find it rude when someone says on an invitation or announcement, "In lieu of flowers, the family request you give to XYZ charity?" How about a wedding invite where it says where a couple is registered? Honestly it is about respecting the wishes of the person sending out the invitation or making the announcement.
I bet some of these are the same people who when they do give money gift a gift card instead of cold hard cash.![]()
But you are not making a request for you but imposing your will on your Daughter, and while you may feel this is your right I wonder if this will become an issue in their social interactions without parents.
