Firefly

I wonder, in vain
Where are you, on Earth
But here
With me?

Like a firefly
In the night
That I stretch to get
But only barely scratch

You vanish into the dark
In a blink of an eye
You leave me lonely, behind
Longing for a single Hi

Why? Are you scare?
Always running to nowhere
Will I ever, possibly
Be able to grasp you for me?
