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
Someday all this hard work, all the tears, late nights, and stress will pay off. Someday I will be the teacher I've always wanted to be. Someday I will be a child's mentor and teach them for the future. Someday I will become a teacher.
