"A THOUGHT FOR TODAY:
I have learned silence from the talkative, toleration from the intolerant, and kindness from the unkind; yet strange, I am ungrateful to these teachers. -Kahlil Gibran, mystic, poet, and artist (1883-1931)"

I think Bran.....
he is talking 'tongue in cheek', the lesson came about from bad examples hence, he is ungrateful to those 'teachers'.
