After the class,I saw him leaving the classroom with my pen.
I saw watching it without saying a thing.
Actually I could have yelled at him like this.
"Give the fxxking thing back to me."
But I konw I would have regretted it.
I was determined to let it go this time because it's technically not my pen.
The pen is completely unfamiliar to me and I don't know where it came from?
I mean I stole someone's pen somehow.
In my case,I know I didn't borrow any pen from anybody,though.
The moment I saw what happened to the pen,I realized how a pen comes and goes.
