This is from kindergarten cop and the best way I have found to assess class background. Plenty of class traitors have contributed to the great idea, so please don't be defensive. Full disclosure my dad was a janitor who previously was in the army (deceased early 2000-ish) and my mom (divorced) was on disability and incarcerated for most of my life.
Yeah. My dad left his post army career as an alcoholic when my moms and he separated. He later went on to become a fine janitor. He was absent but did hold love for us. Short story I also was in the single mom welfare gang, among her boyfriends too... (worst and all)
