Thanks for booking my classes today.
I'm sorry that I cannot open tomorrow due to the typhoon.
We're hoping that typhoon will loose its strength and not affect us badly so I can go back to work as soon as possible.
By the way, its alright if you'd like to have class with another teacher.
I won't mind! Its important that you get to practice English everyday.
So I will see you when I get back.
Take care always!
