My FH and I are both in our 30's and have our own places. We are opting out of having a gift registry, since we are going to spend a ton of time trying to go through what we have already and decide what we keep and what we donate. We are giving the option of giving to a honeymoon fund or donating to a charity of their choice on our behalf. I joked that I should ask people to donate to a dog fund - I really want a cockapoo!
Please tell me we are not the only ones. My FSIL just got married this year and she joked to me, "You just toss it all and get new stuff!"
