Sleepy day

I was playing futsal last night until 23.00 p.m and back home after midnight. I was started to sleep at 1 a.m and woke up at 6 a.m coz I have a class in the morning. It is so sleepy when you have to attend a class in condition lack of rest and tired body. Luckily, I only have a class in the morning. After the class finish, I'm directly back home and continue my sleep time. At 1 p.m I wake up coz a post officer knock my door with hard to deliver a package. Although I wake up coz external factor, but I think I have enough rest this afternoon, and at 4 p.m I have to back to campus for another class.
