Nothing hurts more than when your “friend(s)” choose to believe lies about you from someone else.  This hurts especially when you know a brief investigation on their part, or even belief in you, would have revealed the truth.  The best lesson to learn from this is to be thankful that they’ve showed their true colors now – not 10 years of “friendship” from you.  You can now use that time to develop new friendships and to be more discerning when you choose your friends.
