They don't know.

They think they know you
but they don't know.
They think they please you when they smile
but they don't know.

They think they got you
but they don't know.
They thinks they know the reason for your tears
but they don't know.

They think your very soft
but they don't know.
They think you're happy when you sing
but they don't know.

They think they know you
but they have no idea.
