Engine Driver

I opened the door and closed another he ran out and you followed

I never saw you again

if I had, I would have told you

that it was a test the lesson this time was if you really love someone you let them go

just to see if you taught them well enough to come back

I never saw you again

but the door is still open if the wind closes it I'm afraid

the test will be over and the lesson just becomes my punishment
