Smile Pretty [Lyrics]

Verse 1:
You let him,
break you down,
smile for the world,
oh yes, smile pretty.
Chorus:
Smile pretty,
though, you're falling,
you're a beautiful breakdown, babe,
oh so, smile pretty.
Verse 2:
They'll never know,
you're falling to pieces,
'cause you're smiling pretty,
oh yes, smile pretty.
Chorus:
Smile pretty,
though, you're falling,
you're a beautiful breakdown, babe,
oh so, smile pretty.
Verse 3:
Hide those tears,
behind that smile,
it stops all their questions,
oh so, smile pretty.
Chorus:
Smile pretty,
though, you're falling,
you're a beautiful breakdown, babe,
oh so, smile pretty.
Verse 4:
'Cause they'll never know,
oh yes, they're never know,
'cause you're smiling pretty,
oh so, pretty...
