Over time, most people get busy with their own lives and either put these past events behind them, or never really cared about them one way or the other in the first place.
Just as some of us underestimate to what extent and in what ways other people notice our drinking behaviors, we also often overestimate the importance other people place on these behaviors with the passage of time when we're sober. Most people just don't care, no matter how much enthusiasm they demonstrate while telling tales about our drunken antics.
This explains, in part, why so many people who've made amends report getting a response along the lines of "it was no big deal" from the people they'd offended or harmed, and that they were surprised that they weren't attacked or criticized when making their amends.
Your present and your future need your attention; your past only needs your forgiveness.
