Life as an algebraic equation

We humans have a tendency to forget the 99 good deeds someone would have done for us but hold on to that one bad deed that person would have done. Often I have wondered why life cannot be like an algebraic equation. Meaning “cancel out all bad deeds with good one”, so that only memories of good deeds remain. 99.9% of human beings are “good” by nature and mean well and do well most of the time. How wonderful life would be when we only retain positive memories of people around us?!

Communication

We now have sophisticated communication gadgets at our disposal that enable us to livestream what we are doing at any given time to a loved one on the other side of the world. After 4G, we now have 5G; may be 6G tomorrow. However, I wonder how many of us are able to “communicate” to someone living under the same roof? How many of us are able to open our hearts to near (not necessarily dear) ones?
