a call waked me up

I don't know why, but I really want to cry when I picked up the phone from her,and hearing her voice pass through the line from the other end , her voice hasn't changed its characteristics.she is polite and a little naive . when she called me ,I am sleeping on the floor with a mattress and a bamboo mat under my back. the phone ring waked me up. I ask her where she was at that time, she told me she was still in company , I realize it was about 9 p.m. they must stayed there preparing for the audit which is going to be made by Valeo tomorrow. she needed my help for the audit of tomorrow,some files were not prepared and some jigs are not prepared yet. I asked her why she need go back to her school ,my first feeling when I was told that she will leave the company is regretful then happy if this can make her life better .
last time I wanted to cry is after I saw a documentary which records the ZhiQing's unforgettable period of their life when they were young and sent to northeastern china during political movement. I wanted to cry because I realize how fast a person's life can elapse , how quickly a young man will get old.
