No calculus class

            I felt so sleepy in calculus class but i don't know why.I also cannot focus in that class,but before the class end the lecturer had an announcement that tomorrow they are no class for calculus.Wow,it's make my eyes open.I felt very happy.I also have a physic class at the evening.Today weather cannot be determined,sometimes it's will rain but in the same time it's will hot.Before i entered the physics class,the weather was very hot but after a few minutes the day was rainy and i'm so cool.
