Eddie was singing loudly in the latrine. All the patients were suprise that the guards did not stop him. After the last incident that Old Peter was out of control, he knocked them down. The guards were thinking that Eddie was twice stronger that Old Peter was.

Eddie woke up earlier than the Indian. No one in the ward has waken earlier than the Indian since ten years ago.

Eddie talked to the guard. He need paste for toothbrush. But the guard said the toothpaste was locked up until 7a.m. Instead of toothpaste, he took soap poweder to brush his teeth.

In the ward, everyone was scared of Eddie. He was probably out of school when he was kid. He skipped town to town for survival.

I'm not familiar with "pillar to post." Is that a British expression?

Eddie was singing loudly in the latrine. All the patients were surprised that the guards did not stop him. After the last incident when Old Peter was out of control and had knocked the guards down, they were thinking that Eddie was twice as strong as Old Peter.

Eddie woke up earlier than the Indian. In the last ten years, no one in the ward had ever awakened earlier than the Indian.

Eddie talked to the guard. He needed paste for his toothbrush. But the guard said the toothpaste was locked up until 7a.m. Instead of toothpaste, he used soap powder to brush his teeth.

In the ward, everyone was scared of Eddie. He probably quit school while still a kid. He moved from town to town in order to survive.

(I'm not sure about the details on the Old Peter incident.)
'To go from pillar to post' comes from the idea of going from pillory to the whipping post. Yeah, it is british.
I use it to mean going through a bad patch and experiencing hardships.
