What does the Pretty Little Liars theme song mean?

Answer 1

It basically means two can keep a secret... If one of them is dead! Aha, what's happening in the theme some is what looks like preparing alison's body for the funeral. But lyric wise it's just saying that the person is taking secrets to the grave, and how it's hard to keep secrets. In my option the moral of Pretty Little Liars is to tell the freaking truth! Haha
