Until X happens to you it is an abstract concept. People imagine they understand X, but don’t think much about it. X seems like something other people experience. Those others thought the same until X happened to them. Afterwards they not only viewed X differently, but all other things as well. They never imagined X would have such a tremendous influence on their worldview. There are many kinds of X, some better than others. The experience of X is largely dependent on the mood and expectations of the recipient, so when it happens to you it’s important to remain positive.
