Most people knows and understand all the above mentioned. I think we can see the same words and sentences every where around, either in books, magazines, newspapers, radios or on TV. The thing is when tragedy did happens, these few words are not enough to save the day. The effects will be lesser especially when they know these words right at the beginning. It's just going to take a lot more work then just saying.
举手、举脚 ~ 赞成！但这也得看看受伤的那人是否愿意放下过去、走出阴霾！如果他毅然选择生活在他自己的灰色世界里，久而久之，任起初多热诚想要帮助他的人也会有热情冷却的时候。每个人的生活重点都有所不同，所以他一定要意志坚定、对自己多加信心，终有一日能够从新振作、有所成就、活得精彩！世上无难事、只怕有心人！
