This heart machinery

Outside your house, 1993,
I think I left some essential part of me
I try to trace my steps back
I try to play the playback
But when I see your face, I cannot breathe
And I can't figure out this heart machinery
Sometimes it stops for days and really worries me
And I can't form the words and often I can't speak
And when I hear your voice, I have to leave
And there's an actress in a film who looks like you
And I can't watch that film the whole way through
I'd like to call you up
I'd like to get me straight but
10 years on, it's just too late
The saddest photograph, a splinter in my heart,
is one of you and me, right at the very start
And I can't recognise the person next to you
The mirror fogs
It breaks in two
