He decided to unfriend me. I tried to reason with him, but he blocked me from Facebook, which indicated his lack of emotional maturity that adults should have at his age. I stopped tried and accepted that that’s how life is: we lose some, and we gain some.
I also had a friend block me recently, after I expressed a worry over a situation I noticed. If she was so infuriated by the comment I made out of concern for her wellbeing, I would have preferred that she tell me this. Agree with your assessment. They lack the ability to handle conflict in a mature way. Very sad, but what can you do - life goes on. Great story!!
