This is a bridge in Paris. You hang locks on it with the name of you & your boyfriend/girlfriend/best-friend then throw the key into the river. So even though the friend/relationship may end, you can’t remove the lock. It stays there forever, as relevance to someone once a part of your life.I wanna put a lock on here!
My friend, Katelyn, is in Germany for the summer. She said that as they crossed the Rhine, she learned of an interesting tradition that has recently started on that bridge. Couples will take a lock, and attach it to the bridge's fence and throw the key into Rhine for love and good luck. So, all the way across the whole bridge the fence is covered in locks!
