I am so sorry to not continue with your lesson.
I have a individual condition that I need to walk out of my house early due to work.
Therefore, I change my lesson to early 30 minutes.
It is my pleasure to learn english with you in the morning.
Sometimes, I felt a lack of preparation about lesson.
But, I know that the ability of english is not growing up quickly.
I will study hard until free talking, but I don't know how need long times.
Thanks for your kindly attention.
