My FI and I have both been living on our own for years now and living together for about a year as well. We feel that we have everything we need and, frankly, don't really have enough space to add any more stuff. We have talked about it and would like to have people donate to our favorite charities and animal shelters if they feel the need to give something. My mom thinks that we should register anyway as people like to give the bride and groom actual things. Is it somehow a breech of etiquitte to NOT register?
