so let me tell you a story i heard in my course. it was told by the training centre RSM.

there was this little bird who was so cold that it fell off the branch it was perched on. so here comes a bull, who shat on the bird. so the bird was covered in shit, but cos shit is warm, it managed to survive. after some time in the warm shit, it felt good enough to sing. so it sang and sang and sang till it stirred the curiousity of a passing cat. the curious cat was wondering why the shit was singing. so it dug and dug and saw the bird. seeing the bird, the cat proceeded to eat it up.

moral of the story?
just because someone shits on u doesnt mean he's your enemy (the bull) and just cos someone gets u out of shit doesnt make him your friend.
