In my opinion it is better to take everything easy and I believe that we can turn enemies into friends. When the poet was angry with his enemy and did not tell him about that and grew up his anger . Surely he was not happy , definitely he was in pain and on the other side his enemy was very happy and cannot feel anything maybe if they spoke together they would have reconciled consequently everything ended in peace. But the poet preferred to grow up his anger until it became a big tree and this tree yielded an apple. What do you think of a fruit which is a result of a tree of hatred surely it is a bad , poisoned apple and it looks awesome from outside. What happened next his enemy saw the apple , ate it , died as a result , the poet was happy and relieved !. That is a crazy idea as he cannot feel relieved until he harms or kills . Why hadn't he tried to end the matter in a peaceful way?
Nowadays many courses and books everywhere teaches us how to make friends , how to choose them and differentiate between good and bad
