Morning volley-ball

We are patient fleshman of PT101.
Playing volley-ball on Friday every week is our promise.
However,our exercised-time is so early that somebody may be late for it.
So we make a rule to prevent from lating.
The rule is"The person who late for our volley-ball time should pay the breakfast's money for us.
Although many classmates overslept today,we still had a fun time.
Because the air was fresh,and our minds were flying.
