I still remember, third of December, me in your sweater 
                             Am 
You said it looked better on me than it did you 
                  F 
Only if you knew, how much I liked you 
    Fm 
But I watch your eyes as she
[Pre-Refrain]
C 
Walks by 
                 Em                         Am 
What a sight for sore eyes, brighter than a blue sky 
                 F             Fm* 
She's got you mesmerized while I die
[Refrain]
C 
Why would you ever kiss me? 
    Em 
I'm not even half as pretty 
    Am 
You gave her your sweater, it's just polyester 
    F 
But you like her better 
Fm* 
Wish I were Heather
[Strophe]
C 
Watch as she stands with her, holding your hand 
         Em 
Put your arm 'round her shoulder, now I'm getting colder 
    Am 
But how could I hate her? She's such an angel 
F                     Fm 
But then again, kinda wish she were dead as she
[Pre-Refrain]

Walks by 
                 Em                         Am
