Started out as a little game 
We both could play 
It seemed so simple, superficial 
I lost along the way 
Now I think I’m in too deep 
I’m begging you to stay 
I don’t know why, I don’t know how 
You’ve led my heart astray 

I’ve seen cuter 
I’ve heard smoother 
Tasted sweeter 
I’ve laughed harder 
Acted smarter 
I’ve been wiser 

Tell me why 
You’re always on my mind 
You’re always on my mind 
Always on my mind 

I don’t know why 
You’re always on my mind 
You’re always on my mind 
Always on my mind 

In my life I've met some guys 
Who’ve hurt me with good-byes 
I made a promise to my heart 
To never let a soul inside 
All who know me would agree 
That this is not like me 
Would I believe if someone told me 
I’d trip so easily 

Bridge: What is it about you that drives me crazy? 
I think about you all the time 

Just tell me why
