Go do 100 bad things to one person --- don't greet them, borrow their stuff without returning, invade their personal space ... and so on

After you do all that, go do one good thing to that same person --- defend them in a physical fight, provide emotional support through a difficult time.

See how that person will react. Chances are, they'll remember that one good deed and forgive you for your numerous other transgressions.
