I know that the general concensus around here is that a HM registry is considered rude. I have asked a few friends of varying ages about their thoughts on it, and no one seems to think there's anything wrong with it.
My thoughts are that making it known you want an experience or a service is no different than making it known you want an item. I've read on here that people take issue with the fact that the giver can't be guaranteed that the check from the registry company will really be used for a massage or kyacking or whatever. But someone who gives a vase from Macy's (or whatever) can't be guranteed that it won't be returned for shoes.
So, WHY is it considered rude?
