John Lewis Ad poem

Some people don't get their heads around metaphors so the latest John Lewis Christmas ad passed them by. Anyway here's me take giving the guy a voice:

I feel I am on the moon
And all of you are so far away
My grand daughter is so small
I can hardly see her

I dream of you
Looking for me
With a telescope

But I am so far away
And Christmas is coming
When will I se her again?

The sun is shining today
And the snow is melting
And I am OK thank you
But I still feel I am on the moon

Wait, there' a knock at the door
She's there with a tiny parcel
And a big smile
It's a telescope
Oh my
I can bring her into focus now.
