A story: A man fires a rifle for many years, and he goes to war. And afterward he turns the rifle in at the armory, and he believes he’s finished with the rifle. But no matter what else he might do with his hands, love a woman, build a house, change his son’s diaper; his hands remember the rifle.
Right now in American writing there is no genre as exciting as memoir - the writer can do anything, as long as it works. It's like the 1920s up in this joint. So, I'd say, experiment with how you tell the story. In the best memoir it's not the what, it's how the writer tells the what - meaning and effect through form.
