Years ago much to my amazement a close friend completely stopped communicating with me. I was baffled by the behavior and made numerous attempts to find out why this had occurred. No matter what the attempt there was no response. I was hurt and angry and decided that I would cease attempting to discover the rationale for the break .I fond that as time passed the hurt seemed to grow. I decided that I would write a letter explaining my confusion, and also stating how much the friendship had meant to me. Still there was no response but my anger and feelings of hurt basically vanished. If there is an unresolved friendship in your life it may be worth one more try because even if it fails to reconnect you it may allow the hurt and anger to vanish.
