Mr lamb : So you will. But the world won't. The world's got a whole face, and the world's there to be looked at... what does this line signify?
Through these lines Mr. Lamb inspires Derry to look at the world with positive attitude. The world like all things has both good and bad things. He wants Derry to look at the whole picture instead of focussing only on the half of it, which has shown him negative things in life. His advice to Derry through these lines is to enjoy simple joys of everyday living with people around and nature, ignoring the unpleasant.
