The best people all have some kind of scar.

Emotional scars run deeper than the Nile
and often lie lurking behind a smile.

The pain behind these eyes run deep, I shelter it & keep it within; for these are the scars of my life, not defacing the skin-Elder

Some scars don't hurt. Some scars are numb. Some scars rid you of the capacity to feel anything ever again.

The marks humans leave are too often scars.

Do not trust a person without scars. If they have no scars, then it means someone else is wearing theirs, usually unfairly, and usually permanently.
