Replying an Email

Dear,
Who t f are you?

 Hello my beloved student, i dont know who is this but.. please, next time i hope you can write down your name. So, you want me to teach you personaly? No, of course not. We're not in Highschool Anymore. You have to learn english by yourself.
 Okay my student, thanks for emailing me. Please keep writing an email like this, so you can improved your english sharply. By the way, when i read your email, its like you are using English - Russian lang. Are you Rusky? And your handwrite reminds of Dr. Zomboss on Plant vs Zombie. lol.
 I hope you could understand what am i saying. Bye~

Your Dosen
