A recent spat might have left a bad taste in your mouth, but as far as everyone else is concerned, your name has no black mark on it. There have been no grudges held, so you need to do yourself a favor and forget about the unpleasantness that occurred. Focus on the future and put your best foot forward. They’ve already forgotten all about it, so how about you doing the same thing? Guilt won’t get you where you need to go.
