There's an old guy from another department whom I always meet at the staff lounge.
We've chatted several times and I thought we had a rapport.
Until today.

I was attending a line of people when he suddenly just dropped a few books at the counter.
I told him in a serious tone that he has to queue like everyone else.
His demeanour changed and told me a bunch of excuses that has nothing to do with the fact that he is unwilling to wait for his turn, unlike everyone else.
Yelling from the exit, he even instructed me to call him if there were any problems.
I've heard rumours about his unprofessional behaviour before, but I never allowed them to shape my opinion of him.
Well, I guess today I can.

Not long after, a very snobbish department head came to return his books.
It's a he, but I'm calling him - Biatch !
There were so so many incidents in the past of his rudeness but I always smile at him whenever I see him, though he never reciprocated. Yes, he thinks he's that 'great'.
Gosh ! I was so mad today!
I almost decided to never again acknowledge the above people, when suddenly I recall the previous post, Project Forgive

Inhale.
Exhale.
I shall forgive.
Myself.
I will smile to those people again.
It's for Me.
