I just remembered what an asshole I am

I randomly remembered today the time when I was a teenager and i sold 'dirty' piss to a parolee. I'll give a brief summary of what happened.

When i was about 16, one of my dad's friends was on parole. To stay out of jail, he offered me money for clean urine. One day he came to my house, handed me the container and paid me right in front of my dad and said "if you could take care of that for me then." what was i supposed to do? tell him in front of my parents that 4 days earlier i was baked out of my mind? So I thought over my options, then said "ok no problem" and sold him dirty piss.
