1. "I'm Not The Only One"
By Sam Smith
Complete the gaps with the correct word.
You and me, we made a vow
For _________ or for __________
I can't believe you _______ me down
But the proof's in the way it _________
For months on end I've had my ___________
Denying every tear
I wish this would be _______ now
But I know that I still ___________ you here
[Chorus:]
You say I'm ___________
'Cause you don't think I know what you've _________
But when you ________ me baby
I know I'm not the only one
You've been so unavailable
Now __________ I know why
Your __________ is unobtainable
Even though Lord knows you kept mine
[Chorus:]
You say I'm ___________
'Cause you don't think I know what you've _________
But when you ________ me baby
I know I'm not the only one
I have _________ you for many years
Maybe I am just not ___________
You've made me __________ my deepest fear
By lying and tearing us up
[Chorus x2:]
You say I'm ___________
'Cause you don't think I know what you've _________
But when you ________ me baby
I know I'm not the only one
I know I'm not the only one
I know I'm not the only one
And I know
And I know
And I know
And I know
And I know
And I know, no
I know I'm not the only one
