The beginning of an end

Little child, so tender, so sweet
You've come into their lives
Bringing joy to them all
But what about you?

You're at the onset of a journey
To be tread alone
People you love will die
You'll grow to learn it's all a lie

This beginning they hail about
This journey they harp about
This life brings misery and pain
And ends with you rotting in vain

Look at you, little one in awe
Of lights and shadows that interest you
When you grow a little, little one
The haze shall clear and you shall see

All the shade and gleam
Will show you their true colours
Their ugly face will repulse you
The same shadows that once lured you
