Bad day

Today is not good day for me because I was very sleepy. Today I have four classes. At the class, I became sleepy. So I wiped the sleep out of my eyes. Sleep is very important for our body. How long do you often sleep every day? Now, my sleeping hours are four or five. It is lack of sleep for me. I want to sleep eight hours!!! So if a day were 30 hours. Today's diary is that all because I am sleepy.
