"Tattoo" is a poem written by American author Gregg Shapiro tells the story life of Gregg's father, a survivor of the Holocaust during World War II, and how that event marked his life and even his relationship with his son. Born in Chicago, Gregg has an unscathed life and he realizes how different his path has been compared to his father's. Although Shapiro's father is reluctant to talk or express his feelings about War and the Holocaust, his son understands his suffering and his sorrow, simply by looking at his father's tattoo, a permanent scar he will have that will remind him of dark past days.
