Why would a guy have two women's rings sitting on his bedroom shelf?

It's kind of weird but maybe they are from some girlfriends he had before. Can you see what is says on the slips of paper? They obviously don't really mean anything to him or they would not be out in the open. Maybe they are there to remind him not to give rings out too quickly. Maybe he couldn't remember who he gave them to so he had to write their names on the papers so he can give them back to them. If he ever offers you one, don't take it, it may end back up on the shelf with your name under it. Just ask him like, out of curiosity I've seen these rings everytime I come over here, are they gifts for your mother and sister? Aren't you afraid they will see them there before you give them to them?
