You've always been this way since high school 
Flirtatious and quite loud 
I find your sense of humour spiteful 
It shouldn't make you proud 
And I know your pretty face gets far with guys 
But you make it better not to hide the lies 

Are you sure that you're mine 
Aren't you dating other guys 
Cos' you're so cheap 
And I'm not blind 
You're not worthy of my time 
Somebody saw you sleep around the town 
And I've got proof because the word's going around 
(Don't know you) 

You left your phone so I invaded 
I hated what I saw 
Stupid lying, who's David 
Some guy who lives next door 
So go live in the house of David if you like 
But be sure he don't know Peter, John and Mike 

Are you sure that you're mine 
Aren't you dating other guys 
Cos' you're so cheap 
And I'm not blind 
You're not worthy of my time 
Somebody saw you sleep around the town 
And I've got proof because the word's going around 
Don't know you 
Do do do do woah 
And I know that you try to break me into pieces 
And I know what you're like but you can't hurt me now 

I'm over you 
Do do do do woah 
It's so like you 
Do do do do woah 

Are you sure that you're mine 
Aren't you dating other guys 
Cos' you're so cheap 
And I'm not blind 
Your not worthy of my time 
Somebody saw you sleep around the town 
And I've got proof because the word's going around 
(words going around) 

Don't know you 
Do do do woah 
Don't like you 
Do do do woah 
Don't know you
