No I think it's great. As a friend or family member I would want to buy something that they want and if there is something like say and activity gym on a informal list well there are lots of different activity gyms out there and if the person has their heart set on a particular kind well thats what I would want to buy rather than buying something different and then the person feels like they can't get the one they wanted. Even cot sheets the person may have a theme or colour they prefer.

I think with registries it's just important t choose more then u would expect to get so that the last people aren't left with a pack of coathangers or a dummy iykwim? and also lots of different prices if ppl want to spend more or less or put in with others etc.

If you feel uncomfortable you could word it like if you need ideas I have a registry at... or something like that
