M.D. Golden Rule
The Modern Day Golden Rule is when you only help someone if they hand you a wad of cash or promise to do something back. No free stuff. No kindness. Just a deal.
I only helped my friend move if he promised to buy me pizza for a month.
I didn't help my mom with her taxes unless she gave me $200.
I only helped my brother cheat on his test if he gave me his candy stash.
