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 just started knowing well it ain't no big thing but it's growing

Every day the hurt grows bigger than it did 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 start to flowing it ain't no big thing oh but it's growing
You've got the look of someone who is going...
It ain't no big thing oh but it's growing
