In our everyday lives we meet situations in which we take many things for granted(不去重视).We only treasure things when they are gone. This is a sad truth of human nature. One day，I found myself as a witness to a similar situation.

One evening，I left work and boarded the train. After entering, I noticed something unusual. The center of the car had a few empty seats while both ends were crowded with people standing. I didn't pay much attention and sat down on one of the empty seats. I sensed a funny smell. It wasn't long before I noticed a homeless person sleeping on three scats in front of me. He was bleeding from his nose. Why wasn't anyone helping him?

His clothes were torn and he was giving off a strange smell. Along with the smell, his eyes were dull, watery, and red. Occasionally he scratched himself and people looked at him as if he had committed a crime. As the train stopped at stations and more people came in they covered their noses and faced away from him. All the seats around him were empty.

Suddenly, he began to swear at the people around him. A plain clothes policeman who looked like a construction worker took out his certificate and showed it to the homeless man. The officer, not wanting to touch the homeless man，told him his rights and directed him to exit the train. As the officer walked the man out of the train, the homeless man turned around and said "MY HOME!” and started crying.

A man doesn't value things until they are gone. If he didn't have a home, at least he had freedom. Now he has neither. No one wants to help someone who won’t help himself.

Social networks are a big part of nearly every teenagers life in this day and age. Many teens have QQ，WeChat，or Weibo but little do a lot of teens know that they can be held responsible for everything they post for the rest of their lives. Everything yopost online is part of a digital footprint that can always be traced(追踪)back to you. That includes every post，even like, comment，favorite and forward that yohave ever committed. All pictures you’ve posted or will post have been stored in a digital database, and it is the companies' right to keep all of these documents that yobelieve to have been deleted or hidden.

With every post comes a consequence; whether it is good or bad, what yopost could be seen by anyone. That is why yohave to be very careful of what yodecide to post or comment.

If yothink yoare safe from Servite finding out about one funny comment yomade six months ago on a meaningless picture, yoare probably wrong. Recently, a senior, Aaron, at Servite learned this lesson the hard way this year. He wrote a series of ugly comments towards Connelly girls on a web page, ignoring potential consequences.

This student, however, did have to face consequences from Servite as he was removed from all of his leadership roles in the school. Surprisingly enough, he fully agreed with his punishment handed down by the administration and fully understood why he was given such severe discipline(惩处)."When yoagree to come to Servite, yoarc agreeing to defend what Servite stands for，" the young man said. "That continues past the hours of 8 am and 2 pm. It’s at all times.

So，next time you’re about to post something yothink could be received as offensive or inappropriate, think twice, think again, and don't press send.
