Musings on a Piano

I have a piano,
I play it as a treat.
I have played one song since I was eight,
The song, is never complete.

I eat while I'm playing
I sleep tapping keys
The seat is a toilet
My schooling is on 'freeze'

I've played the same song
Every second of my life
I don't think I'll ever end
Even if I don't get a wife

When I started playing
I had lots of friends.
Until I started to play on the piano:
"This is the song that never ends"
