I don't know how many roads there are to enlightenment, but I do know there are a lot of ways to make all of our days brighter. It obviously helps a lot when people do something nice for us, but even those who don't notice us can do it by acting really extra or saying something funny.
For instance, my family heard this one lady say, "Talk to the left 'cause you ain't right!" to her kid, and it hit us at such a perfect time that we all remember it 20 years later.
I can't promise these people will make that impression, but they'll make a good one.
