is it not okay to get angry?

I got upset one day
At something worth my emotion
I used my anger in an appropriate way
Only to be met with confusion
What was I so mad over?

I tried showing them the parts
The places of doing instead of talking
I tried to show them it wasn't so far
To the land of actually accomplishing
Still, they want to know what I'm mad for.

Then, I saw a glint of something more.
Of something I had not noticed before.
A gleam of fear hazed over their eyes
As I forcefully expressed my points.
Maybe I will go away if they close their eyes.

The fear was rather startling
As it came to stage and made itself known
It is pushed to the side by irritation
At having to deal with my eccentric ways
They will roll their eyes when I am done.
