When you reach a certain age, the people around you expect you to have a sense of wisdom about you. You’ve gone through the grind of life and have made mistakes along the way, hopefully learning from those mistakes. That learning is where you gain that wisdom. But when you fail to display that wisdom, you turn out disappointing a lot of people. People who look up to you, especially.
But of course, no one is free from making mistakes. They do not escape you, no matter at what point in life you are at. Wisdom (and maturity) would dictate that, upon realising that one has made a mistake, one should express remorse towards one's actions and try to make up for it.
But of course, that is contingent upon one realising that they have made a mistake and are brave enough to own up to it in the first place. May all of us be blessed with people who remind us of common decency and also be given the courage to do what’s right, even when it’s difficult to do.
