I’m so sorry Kelly....

Hi [이름]!

Thank you so much for your message. Anyway, you don\'t need to worry about your class yesterday. I totally understand your situation. If you cannot really study because of your hectic schedule, you can also put your classes on hold on the website. I know that you are also busy. So, smile and have a good day. I will see you again :)

I thought that I could take our class today before my schedule, but situations are always changing, so I couldn’t spare slack time..

I know how sad when the class was cancelled as a teacher, so I wanted to take up your call and explain the situation on my voice.

But, because of my poor English speaking, I failed to say what I want to say.

I’m really sorrrry8ㅅ8 BTW I read the second article and again, I decided to lessen my smartphone using time^^
>> I\'m really sorry. By the way, I read the second article; I decided to lessen the time that I use my smartphone.
Last night(actually today), I fall my smartphone upon my face and it really hurts. The article said that falling smartphone means time to sleep.

>> Last night (actually today), I dropped my smartphone on my face and it really hurts. The article mentioned that if you are dropping your phone on your face, it’s probably a sign that it’s time to put it down and get some sleep.
