Really easy question, 10 points first answer?!?

By the way this is not an easy question. Anyways it basically means the poet was angry with a friend and he held it back and kept it inside. He got angrier and angrier but he feared how his friend would react. He would cry alone but be a smiling happy face infront of everyone, decieving everyone. The fear and anger grew then his friend finally found out his anger and his friend knew it was the poets. The friend understood and they were back to normal. Warning: This is my interpretation and others may have differen't perspective and the poet may have had a totally different meaning.
