...how to hurt...

There used to be a time when I was too afraid to hurt someone, I felt pity for her/him.
Today, when I´m much older and "blessed" with life experience, I´ve come to learn that it´s often much better to hurt someone than keeping on out of mercy, and destroying a life.
To hurt, I believe - it´s in fact another building block (using black tar and feathering), which can be used, and is often a necessary ingredient, to built a happy life.

I didn´t know.

But I´ve been hurt myself several times, and in the end, those hurts turned out to be good building blocks to build new cosy rooms in the house of my life.
