Pepper /ˈpɛpɚ/

Humans are like flavors.

You can't be a good person forever; because that way you're nothing but a grain of salt.

You're everywhere and everybody knows how you taste.

Even if you are evil, lustful, rude, or helpful; you have your own flavor that differentiate you from this world. Like one specific spice; you won't be replaced. It's your uniqueness that will make you taste delicious.

p.s. I like chili more than sugar.
