Voices inside the head


It kills you from inside,

Haunts every night

Paint a smile

Of no joy

Thinking you will find what lacks behind.

Say, Hi! To your friends

Give them a smile

Yes, I’m proud of you, boy

Even it kills you from inside.

The Moon

Silent and still, the moon shines bright
In the dark, clear sky
Peaceful and calm, the night
A soothing balm to the weary eye

The moon, a glowing orb of light
Illuminates the path ahead
As the night wind whispers through the trees
And the stars twinkle overhead

So let us lay down and rest
And let the moon and night provide
The peacefulness and solitude
That we all need to feel alive
