Understanding the complexity of human is a course on its own that need to be study and it require more hardwork,but hardly enough,no matter the number of years you spent is study the course,you might still not know it fully. Human being is complex but there are times where the complexity of some might be as a result of past experience and encounter in the journey of life. The more we accept others for whom they are,the more happy we become.
