- Most of my friends are black.
- I am someones strength while someone is my strength and we all are dependent on each other.
- I have a tail. Sometimes long sometimes short.
- I have two teeth.
- I am a spinach for rich and for poor.
- Things might stop if I do not exist.
- Some of us glow in dark.
- Before you start guessing, just to let you know, You need to be aware of me.
So, find the spinach that everyone eats.
Spinach is a metaphor. "Everyone" are non living things.
