It Ain't No Big Thing (but It's Growing)

You're losing interest in me and it's showing
It ain't no big thing but it's growing
The pain of heartbreak I've just started knowing
It ain't no big thing oh but it's growing

Every day the hurt grows bigger than before
But I'll pretend that I don't know this if I can hold you one day more
You've got the look of someone who is going
You're gonna leave me and it's showing
A little tear I can feel starts to flowing
It ain't no big thing oh but it's showing
It ain't no big thing oh but it's growing
