Girl on Platform 2

I caught you looking then
Do you know?
Wonder what about me
Intrigues you so?

I'm medium build
With short brown hair
My green eyes smile
Like I have no care

I'm observant
Or so I'm often told
Which is why I caught you
Being so bold

Do you want to talk?
Should i say 'hello'?
But I'm unsure of
Just where to go

Why do you look?
You're so very pretty
Can't imagine what
You see in me

Wouldn't know where to start
To talk to you
I'd get all flustered
I often do

The train's due now
Its coming round the curve
Should I sit by you?
No, I don't have the nerve.
