The foreign student was so rude that I was literally shaking with anger.
I didn't realized the extend of my anger until I saw that my fingers were shaking.
I was so overwhelmed that I walked over to him and gave him a piece of my mind.
He said something but I walked away, ignoring his words just like how he ignored mine previously after his 'drama'.
I was really pissed.

I vented to my friends via Whatssap. They were sympathetic of course but were worried that there might be repercussions.
"Careful when you deal with people like that. Obnoxious people do obnoxious things.
He is after all, student of this private institution.
And we are staff of this institution."

I was really upset because they made a good point. The safe professional way was to have let it go.
But the silly naive careless sense of justice in me just couldn't let that rudeness slide.

I went to yoga and had dinner with a friend.
Chatted jovially on a wide myriad of things.
Her brothers' health, the many others suffering the similar illness, about our own health, food, work, how to get along with the people at work.
It was fun.

I gained back the positive energy and now I am able to see the prior incident in clearer view.
I had foolishly followed that foreign student's trail of negativity.
I allowed his rudeness rubbed into my own ego.
I had the power to be the bigger person and let it go.
Not because I'm condoning that behaviour.
I shouldn't have let it affect me personally.
I should have viewed the whole incident as his problem.
Indeed, his rudeness is HIS problem.
Hence, I shouldn't be affected.
