They know all our weaknesses and yet support us.

All the teachers know the weaknesses of their students. But they never leave you like that. They guide you, support you and help you overcome your weaknesses. Nobody else does that. They walk you out of the mess you you put yourself in with their guidance. They are the one's whose main focus is to bring out the best from you. They never laugh at your weak points, they make them strong with their helping hand.
