Rejection

WHat is the nature of rejection? Where does the hurt lie (lay)? Rejection of part does not necessarily transfer to a rejection of the whole. Not every one wants what it is we want. perhaps it is an over involved sense of self leading to an greater feeling of rejection. It is therefore impossible to have ordinary relationships with fellow man due to an acute machinism that shows all rejection not is a reflection of the rejector but a magnifying glass upon the rejected?
