FIVE RHYMING RIDDLES
From What Am I ? Vol. 2 
Zack Guido

1)
Nobody really reads me,
Nobody really needs me;
It takes two different types of skill
To write me and remove me.

2)
I can't go from here to there,
But I can go from there to here;
But that will only happen
If I disappear.

3)
You find a lot of me in a library,
Though there's not supposed to be
A lot of me around;
People question my presence
When lonely trees fall down.

4)
Without wings, yet I fly,
Without eyes, yet I cry.

5)
Everyone leaves me,
But few people see me;
Better than a name,
I identify uniquely
