Everybody thinks themselves the centre of the universe

And this is the point from which we converse.

I, me, my, mine, myself

Are the centre of my own circle.

He, him, his, his, himself

Are any boy or man I may encounter.

She, her ,her, hers, herself

Are any girl or woman whom I mean.

It, it, its, itself

Are anything around me that is lain.

We, us, our, ours, ourselves

Are me along with any human being.

They, them, their, theirs, themselves

Are any people or things that do not interfere.

You, you, your, yours, yourself, yourselves

Are any person to whom you may speak.

Thus, we've come to the end of our pronouns

Which we sometimes use instead of nouns.

I hope I have done the task, indeed

Not just a useless deed.
