While taking the bus down Haight Street towards Market yesterday, I overheard a gentleman telling his (hard) life story to another passenger. His story built to the point that he was eventually busted for possession of drugs and sent to jail. He was sentenced to eight years but only served 2/3rds of that, having gotten out early for good behavior.
However, the person he was telling the story to couldn't do the math and couldn't understand what 2/3rds of eight years was. "So you were I jail for eight years?" "No man. I said I was sentenced to eight years but only served five years and seven months." "But wait...you said you got out after 2/3rds." "I did - that's five years and seven months of eight years." "But wait..."
And on and on and on, until I got off the bus at my stop.
