Dear teacher!
I am Mickey. Today, I write this mail. I apologize to you for my mistakes. I'm so sorry about that. I know I did something very bad. That's very awful and I have regrets about that. I beg your pardon and I promise I won't do that one more. Before I go to Korat I tryed to connect you but I couldn't. I didn't have your E-mail and your phone number. If I tryed more, you wouldn't be in a bad mood. I hope you will sympathize with me. I am so sorry again.
Mickey.
