It takes little to be honest, really. Even if it's just a little bit of honesty. If someone can't put that effort out, and would rather instead, inflict emotional pain by excommunicating, then that's not cool.

One thing about life too.. often people get the feeling that someone else is too close to them so they instinctively back away (though should still offer explanation IF they actually cared) and THEN when the other person begins to accept it , dusts themself off and carries on, that same person will come back again. A stupid teeter-totter or tug-of-war. Its bizarre and rather lame.
