Some people just find joy in creating tension and causing relationships/friendships to crumble. My guess is they envy the friendships others have and they themselves can never hope to have the same kind of friendship. It is sad when a person envies and then goes on to destroy.
I just hope that the person/s who have been smiling inwardly with glee will learn that he/she/they cannot win by causing others to lose. What value is it when one wins when in the process one causes others to stumble rather than winning with pride due to personal ability?
In the meantime, a friend needs a hug. Being bombarded with many negative things in one day, starting from early morning was not an easy thing to swallow.
