I recently recieved an invitation to a couple's housewarming party and on the invitation it included registry information. I thought it was rather tacky to include registry information on the invitaiton in the first place, but I was mainly blown away that they had registered for a housewarming. I had never heard of that before. They are engaged at the moment so maybe they just couldn't wait for a wedding shower, but still. I didn't think you should expect gifts at a housewarming. I thought it was more of a 'Welcome to my Home' type thing. Have you ever been to a housewarming where the owners were registered somewhere? Is that a normal thing to do? Or is it obnoxious?
