Carving on the rock, ground and water

I thought I was carving on the water.
However, when I was angry today, suddenly I realize there were some big rocks behind the person that I was angry at.
I looked at the rock.
And I knew that I'm still carving on a rock......

"Three Types of Anger"
There are three types of people in the world.
What three?

One who is like carving on a rock,
one who is like scratching on the ground and
one who is like writing on the water.

What sort of person is like carving on the rock?
Imagine a certain person who is always getting angry
and his anger lasts long, just as carving on a rock is
not soon worn off by wind, water or lapse of time.

What sort of person is like scratching on the ground?
Imagine a certain person who is always getting angry but his anger
does not last long, just as scratching on the ground is
soon worn off by wind, water and lapse of time.

And what sort of person is like writing on the water?
Imagine a certain person who, even though spoken to harshly,
sharply, roughly, is easily reconciled and becomes agreeable
and friendly, just as writing on the water soon disappears.

[from Essentials Teachings of the Buddha]

What type of person are you?
