It is a natural part of life. The strength of a relationship is not how long people know each other, or how much they like each other, chemistry, or personality. The strength of a relationship is forged and tested through resolved conflict. Conflict is the stress test that will strengthen and deepen relationship. Sad truth is, people don't want to go deeper.
People let their personal wounds fester and turn into stinky sores.
Some people don't say very much, feeling like they don't have much to say. Some people say too much, whatever comes to mind. But people are not listening to each other, and interacting, and dialoguing with others. We all come from different worlds, heritages, perspectives, and it only enriches our lives to see and seek to know the world in full technicolor.
