A letter to a friend

Dear Tim
It is Thursday night, and I am sitting in my classroom to write a letter you! The weather is quite chill and windy today, and this kind of weather makes me don't want to stay outside and could back home as soon as possible, aspecially tomorrow is Moon Festival.
This morning I was so busy to deal with all the daily routines, It was taking me some time. But I still had something different today, this early morning one of my classmate, Ken came to my office to see me. We had a little chat, and ate lunch together, that was quite suprising me, because I didn't expect he would pop in and stayed for a while.
After he gone, my nightmare was coming. That was because I had spend to much time with him, so I didn't have enough time to get my work done. Then I had to off and left my placement on time, otherwise I would late for my class. luchly, that did not happen at all!!
How are you and what are you doing recently? Have got any plan for the weeken? Hope we could spend sometime together for the Moon Festival, to have aBBQ! Anyway I hope you can enjoy the weeken and have a good time though, see you soon.

Best wishes
Allen
