Physics

Add it up now it all seems to make more sense
When it comes I gotta know
Wanna know how it ends
Can't be sure, but I think you'll fit quite well
'Cause you got all that I want as far as I can tell

But if I'm afraid
Its because of
All that he might take if- [?]
If you might let go[?]

Now she stands in the doorway and peers right in
The silhouette of her figure
The scent of her skin
Just one look at her body is all it takes for me
She'll make me a liar if I let her in

But if I'm afraid
Its because of
All that he might take if- [?]
If you might let go[?]

But if I'm afraid
Its because of
All that he might take if- [?]
If you might let go[?]
