I keep a book of the people you might know
I keep a book of the places that you go
And when we speak if you look a certain way
I search for hidden meanings in the words you say

When I go out I hope that you'll be there
And if you're not I pretend hard not to care
I find the names of the films you go to see
I write them in the book and take them home with me

I don't know if it's true
But I bet you've got a thousand lovers haven't you?
Now who's the one you're looking at?
It won't be me, we already know that

I keep a book of the phrases that you use
You buy your clothes, I know the colour that you'll choose
All the facts are recorded in a list
And double-checked for details that I've missed

Oh would you call it love?
Or just a sad obsession I can't shake off
I want a share in you
And know about the secret stuff that you do

I keep a book, I hope it never ends
And if we're good I think we can be friends
I'll make sure it's for no-one else to see
It's our book that I keep for you and me
