My work friends are throwing me a shower at my job. I am 36 years old and have been living with my fiance for four years. We do not need anything, not even money. I guess you could call me and the fiance kind of hippies. We don't really care about material possessions or having a lot of "stuff". Because of this we do not have a registry. My friend who is putting together the shower asked me what I wanted. I told her that gifts aren't necessary. She is insisting that we ask for something even if it is gift cards. Is it against etiquette to tell my friend we would love "experiences" like tickets to plays, musicals, or museum memberships? Or can we ask friends to donate to an animal sanctuary in our name? What do you do when you don't need physical items and are having a shower?
