9mm
My boy's come home and given me a centerpiece: a white rose in a nine-millimeter vase. The stem is stripped and grimy from its stay in the barrel, and dry: a nine doesn't hold much water. Ammo is buried at the end of the clip for balance: I am told I should not keep it on the flag he was sent with: the gun might stain it. He once asked me what a ploughshare was; I told him I didn't know.
