which one is true "no one can replace you" or "no once can't be replaced by you"? and what do those mean?
They have different meanings. "No one can replace you" means that there is nobody that can take your place, because you are special, you are unique, you are the only one I love, etc.
"No one can't be replaced by you" means that you can replace everybody else. For example, if I don't like my friend, I can replace him with you. If I don't like my brother, I can replace him with you, and so on.
