Lyrics:

I apologize, I should've kept it hidden
Under wraps and out of sight, at least in the beginning
But I wanted you to see what you meant to me
Turns out that wasn't smart
A sleeve is no place for a heart
Wish I could take back the secret that I told you
But it's too late for that, now you know the whole truth
Three stupid little words, you never should've heard
But I let down my guard
A sleeve is no place for a heart
Take one last look before it's gone
It's time I put it back where it belongs
Next time I will know not to let my feelings show
I'll keep them in the dark
A sleeve is no place for a heart
