Apostrophe Poem by Elia Michael

Perhaps they think I am not that important
After all, I am such a little sign
At times I'm used to show a word is shortened
And I can show that this is yours or mine
Or his or hers or theirs or even its
To show exactly who has possession.
That was when I was used and loved to bits.
Yet now, some mention me with aggression.
He said I was not needed, redundant,
But I do strongly disagree with him.
I think I am really so important.
(The chance of me converting him is slim) .

I make the written world so very clear
But for how much longer will I be here?
