Subject: Apology for drinking
I hope you are doing good. I am also good here. I write this letter to apologize for drinking alcohol. I know that knowing that I drink would have hurt you a lot. I know that this was dad’s nightmare if I start drinking and would have hurt you as well.
I am sorry for doing so and I promise that I will restrain this habit. I also ensure that eventually, I will quit drinking. Please take good care of yourself.
Yours son/ daughter,
