I worked for 12 hours today.
Today was a day of SD, SD is short for shut down.
Our office's machines keep running to produce papers for 24 hours,until SD.
SD is about 2 or 3 times a month.
In a day of SD, we clean and fix those machines.
It's hard work because our office has a lo of machines,and each machines are large.
And machines get dirty between last SD and next SD.
Because of it, we mostly have to do dirty work so I don't like SD.
By the way, I went to drugstore after working.
I bought medicine to cure injured my lip there.
It looks like a seal.
When use it,just put on a injured point. And it covers the injured point and cure that quickly.
I hope to take effect and reduce pain.
