My father's scars

As a child I often asked my father to tell me about his scars.

Most of them were from [hammering] nails or other things, but I never asked for grand stories of fights from him. They all had [detailed] stories. Something that marked them as fitting on his yet unbreakable skin.

Looking at my scars, I cant recall where most of them are from; but maybe I went out collecting small things [he] could ask me about so I’d have chances to tell [him] stories
