he was tired

About eight pm I asked my son to turned off the TV and read a book. He needs to read his book to study even though there is no school tomorrow. He got upset and was begging me to let him watch one more episode of Speed racer. I told him no that he had watched enough TV. While he was reading the book he was yawning . He was so sleepy but he did not want to go to sleep. I helped him brush his teeth and put him to his bed. It was a little bit early for him because his time to go to bed is nine pm but not tonight. I told him to go to sleep early because he was so tired already.
