Nothing interesting.  It is disappointed class!

The lesson runs between 9pm to 10pm.  The instructors might have been tired. They don't want to serve balls to us.  We just practice serve and return ourselves.  2 men play singles in last 15 min. for tie break.

Even though my arm was sore and a little pain for one day after lesson. To avoid damage my arm I do not join any club this year.  I plan to play twice a week including the lesson.  That's it.
