I don't know if I understood it correctly, but I have a vague understanding of what you wanted to say. True, that we always make our mark and leave an impression on people whom we knew along the way. And although we think we know, there are still things left unsaid about how they truly feel about us. All the more reason why choosing what we speak and what we do regarding how we react to everything around us can change a moment of our life.
Why do I feel like explaining?
