ungratefulness

I don't understand why some people tend to take things for granted and don't realize what is happening because of them. People tend to put themselves as the priorities but not all does. Pertaining to this fact, people who we care for are often on one of our top priority list, however when this happens people too tend to expect for something in return. This makes relationships sour, bitter or sweet. Its difficult to learn the art of ignorance, that will help not only to maintain the relationship and also prevent unnecessary problems.
