Say you are saying an apology... it doesn't mean anything until your ACTIONS show it. Words do not pay the deeds you have done, you need to prove it to others, that you are truly sorry, AND change your habits. If you don't even change your habits, then people will know that you weren't even sorry in the first place, and that you just said it to get it over with. Words also do no pay what you say. If you say a word to your family that isn't so nice... words can't pay unless your actions show it.
So what I am trying to get at is words do not pay, unless your actions show that you are truly sorry, and that your actions backup your words.
Hope this helps, have a good day. c;
