Q: Metaphorical

I have to explain myself to the likes of you
But it's like banging my head against a brick wall.
But if I keep banging my head against the wall,
Maybe eventually I'll make a dent.
I have to prove my existence to you
But it's like getting blood from a stone.
But if I keep squeezing the stone,
Maybe eventually a drop will fall.
I have to be so many things to please you, world,
But it's like taking a horse to water,
You can't make it drink.
But if you force me to do what you want me to do
Expect me to spit in you face.
I'm not some freak for your show
I won't be made to jump through hoops.
I refuse to give into you, world,
I won't let you win,
You can take me to water
But you can't make me drink.
I'll keep banging my head against your walls
And one day you'll see the dent.
