Classic or dud: Chapter-1 of my first book.

I'm writing my first novel and I want comments on my first chapter. I need the not so perfect parts pointed out so I know where to focus on.
Thanks.

Chapter 1

But bathroom showers are better. Just what I thought as I streched my hand towards the shower knob.
They don't have the itch to wetten the whole of the world. They know the details of their water supply.
It's not like standing under a dark, grey sky with fluffy clouds, neck bent backwards, mouth open in anticipation of rain water falling right into your mouth when it's raining heavy enough to think that.

"You need a wider mouth", said the voices.
- Hey, you are not to be a part of this written piece!

Yeah, so, I was saying that I like lemonade.

"Lemonade needs water too, idiot!" interrupting again.
- Shut up! How dreadful you are.

I twisted the shower knob and ran towards the opposite wall.
As it was a good shower it didn't drop droplets catching me everywhere I went like the stupid rain.

The voices screamed again,"You call yourself the stupid rain!" And went the roars of ha ha ha.
- Duh!

The water fell on my feet. My small, ugly feet. Some of it splashed on my legs, too.
I entered my hands and arms in the falling water. As it hit my arms some pearls reached also my warm body. My wrist gets excited at times like this, my hands, with playing fingers, started to make the noise of falls and splashes on the dark blue tiled floor.

The cold chilling water coming straight from the tanks standing in the very temperature of the winter degrees. Mumma tells me not to bathe in cold water. She says the maximum temperature outside is 19 degrees celcius.

"Mumma is right" they said.
- Mumma is not here.

Mumma is an interesting lady. Mumma trusts the weatherman and she trusts the bus driver.
Mumma doesn't trust me. Mumma's not the kind of mumma she claims to be. But that doesn't stop her from being an interesting lady.

Ah, I talk so much of mumma but that doesn't make me less than 15. Mumma understands me more. More than any dad on this earth. Yes, I'm finished.

So, I started jumping with my hands in the chilling water. More and more drops fell on my body as I started getting used to the chill of the winter water.
I jumped and danced and twisted the twistable parts. Soon it was time to feel like wanting water all over me. I jumped inside and continued while rotating. Breathing became harder. Myself was very susceptible to cold. If I would know what one thing on earth attracts the cold virus like I do I would get it pulled out of me.
Well, this bathing stuff was my way of preventing the noisy, bubbly, dirtying of hankerchiefs in between of the classroom when your seat partner shifts his ass to the colder part of the chair.
No, the other colder part.

When I was wet enough I stopped all the shaking and untwisted the shower knob.
I put shampoo. Rinsed. Conditioned. Soap on my body. Rubbed it. Scrubbed it. Washed my genitals, then hands. Showered.
I also did all that I am forgetting now and pulled my towel on myself after a last shower.
My head felt all cool and funny. The headache was gone. It felt like the tongue feels after a strong mint toffee or a chewing gum.

I disturbed the past setting of my hair with my palm and fingers and got it to that present. Rubbing my scalp I opened the door and I saw straight in front of me. The pretty Crystal stood there in the mirror.

I still love her.
