I know that what you are thinking about me after the last night incident. But my dear friend whatever last night happened was just my big mistake. I should not have abused you and slap you dear. It was just done by the mistake. I was totally out of mind my brother.
Now whatever I can do is just make a sincere apology for my big mistake. Your angriness with me is totally valid my brother. But it will just result in the breakup of our long friendship. I do not let it happened that is why I am writing this letter to you my brother.
Every human is bound to make mistake, I have also done the same. But it is also fact that every human learn from his mistake I have also learnt the lesson. I promise you my dear it shall not happen again in future.
Please! Please! Please! Forgive me my brother and sweet friend.
Your best friend,
