There's a lot of things in life that you can undo, you can take back and no one will ever know. Words aren't one of those things. Yes, if you say something, you can go back and correct the situation, apologize and take ownership, and you should each and every time. Right? Words themselves cannot be unsaid. If you say something mean, vulgar or hurtful to somebody, they can't be taken back. The person may forgive you, but you can never take those words back.
