Some moonlight-youths may laugh at the patrol cop in the night's fatigue, thinking moonlight-youths are also busy overnight but feel easy and happy. In fact, it absolutely can not be said in the same breath, when I was a youth also had some sleepless nights in free mind, because I didn't need to take care anything and I didn't care anything. I can sit down and lie down at any time, or even go home to sleep. Those are the days with no duty on shoulder, if anything happened, moonlight-youths can usually go away. Patrol officers have to face almost everything!
