Depends on the friend, so much.  But typically I start with monetary debasement with clear anecdotes (big mac price chart e.g.).  I ask questions that lead them to the conclusions like "would you rather leave your cash in the checking account or invest it?" "why" Then back to inflation again and debasement.  Try and tie those two things together tightly followed by Debt-GDP money printing.  Then when the color leaves their face and they see the financial apocolypse on the horizon,  I replace it with the rising orange sun.
