I am writing this email to apologize for the way I behaved with you yesterday. I want to clear all the misunderstanding that is there between us.
Today I would like to tell you something that I have never told you before. If I have understood the meaning of true friendship, then the person responsible for it is you. I still, remember the days when we used to have fun together during school days and when you used to stand up for me whenever I was punished. I still remember how you used to help me with my homework. You protected not only as a friend but also as an elder brother.
But, I don’t want to lose all those lovely memories only because of one misunderstanding. I am sorry for behaving with you rudely. I was not aware of the situation, so I shouted at you. Please forgive me my friend.
Your best friend,
