Story (about half of it)

This is my story/poem so far. It's about half way and im stuck on the rest so im having a break before continuing it! What you think?

A long time ago, when I was a lad,
I had a small friend, just like everyone had.
It all began on a dull rainy day,
When it was far too wet to go out and play.
I sat on my own, at the dining room table,
And drew as good as I could, the best I was able.
Alone with some paper, a pencil and pen,
I drew a small character who smiled, and then,
He came to life to my shock and surprise!
I couldn’t believe what was before my eyes.
For there stood my drawing with as much life as me,
A fun little friend, for my company.
We waved at each other and then we both knew,
We could have lots of fun together, just us two.
We would swing on the swing, for hours on end,
Just him and I, just me and my friend.
One day, when he’d been swinging higher than high,
He let slip of the chain and flew through the sky.
For such a small fellow it was a hugely big leap,
Yet to my surprise he hit the ground on his feet.
I’d play his favourite tunes for ages,
And he’d help by turning the pages.
In all the time we spent together,
My parents, aunts and uncles never,
Seemed to see the friend that was mine,
I’d find out why, all in good time.
On my toy cars I was too big to sit,
But my small friend was the right size to fit.
How long we spent playing I couldn’t say,
But we became better friends day by day.
At school I discovered, much to my glee,
That every child had a little friend just like me.
When playing with a puzzle he always knew,
What piece would work, which piece would do.
He’d use all his might to push it towards me,
Then once completed I’d lift him high to see.
(verse not yet written)
I kept playing with my friend but my sister did not,
She grew up too quickly and completely forgot.
She forgot about her friend and never saw her again,
Why couldn’t she see her? I thought, and then,
I realised that you’re not a child for long,
Some people grow up too quickly and then it’s all gone.
So then I decided that I never would end,
The fun and friendship I had, with my little friend.
