Eighth grade boy's bathroom. You're washing your hands after a tremendous shit when your best friend Tommy walks up to you and says, "Hey, you want to try smoking marijuana? I just bought it from this high school kid."
Right then and there, you're confronted with something you know little about. There's a mini-battle being waged inside of you. Conflicting information about how drugs are bad and how marijuana is harmless. How much do you trust your best friend Tommy? How much do you want to heed your parents warnings? Was Nancy Reagan or Snoop Lion Dogg right?
And the answer is: Flip a coin. You never had any free will to begin with.
