A girl I go to college with was banging on about getting married and a lock and Paris the other day, makes much more sense now I've seen this. She's just gone and got an open, heart-shaped padlock tattooed onto her ring finger as well, to be tattooed closed when she gets married. I think it's a bit sad that getting married is so important to her - she's not even seeing anyone at the moment and yet she has all these plans.
