Too much time spent looking up

He always had a thing for looking up.
To stars or birds, or whatever it was,
that happened to catch his eye.
take his fancy for a while.

He always got caught up in dreams.
Lost in worlds I couldn't see.
I knew he would come back before too long
But then once again he would be gone.

He would sit at the window
gazing out for hours on end.
Watching birds come and go
Not even noticing the world move on.
I couldn't break into his dreams
No matter how hard I tried.
I wasn't allowed to know
What it was that had him so entranced,
Maybe he was searching for a song
Long since passed,
Forgotten and gone.
Or maybe not.
I could never tell and if I asked I knew
He would simply look me in the eyes.
His big black irises engulfing mine.
And then his blank face would break into a smile
And he would reply,
'Sorry. What did you say?
I was lost in my own head again.'
