Metaphoric poem final draft

I am an Encyclopedia
An open book
But hard to understand

I serve a special purpose
To give people knowledge
To convince them
To get them on my side
I work hard to help others
Especially the ones in need
All they need is info
All they do is plead
They don't want help from me
I'm just boring on the outside
But if you get to know me
I am pretty interesting
So c'mon ask me things
I will not lie to you
I hold many thing
Not only facts
But secrets, too

People say that I'm so intellectual

But that's not the true me

I know lots of things

But funny things and jokes
You probably think I'm a know it all
But I promise that you'll love me

I may look just boring

But on the inside

You'll see how colorful and filled with different things

I help you with homework and cool facts
Not interested? Cant blame you
I am an encyclopedia
