    It was nine in the evening. I was on my way to my bedroom after brushing my teeth. As I was passing the living room. I saw my brother, Aldo, lying on the floor watching TV. He always did that every night. He refused to go to bed and chose to sleep in front of the television. I decided not to say anything and directly went to bed.

    I was half asleep when I heard a scream from the living room. It was about two in the morning. I jumped out of bed and rushed towards the voice. In the living room, I found Aldo crying. His right hand was on his right ear. He said, "Help, help, help. It hurts" Then, he told me that an insect had entered his ear. I was quite sorry for the insect. I figured out it was an ant. I imagined how miserable the ant was. Since Aldo couldn't stop crying, I decided to take him to the hospital. Soon after our arrival, a doctor in charge examined Aldo's ear. He then, used a pair of pincers to take the insect out. I was so surprised to
see the insect. It wasn't an ant. It was a young cockroach. Gosh! It was as big as a baby's little finger.

    From then on, Aldo never slept in front of the television any more.

What is the main idea of paragraph two?
