Criticise Constructively

I write, not because I'm good or bad,
I write because it makes me glad,
So sharing these small things with you,
Is a very hard thing for me to do.

My thoughts don't come out right sometimes,
They come out short and full of rhymes,
And childish poems, they may be,
But they still mean something to me.

So whether you like them a lot,
Or think they should be left to rot,
I'm asking for some courtesy,
Criticise constructively.
