[Verse 1]
When we met, I just knew
That I already loved you, true, true
I didn't even get it, why
Why you gotta stare with those eyes
I'm right across the dance floor
Like it was just last night
I didn't even get it, why
Why you gotta say goodbye

[Refrain]
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days

[Verse 2]
Boy, I let you in
You didn't even have to knock
An extra key on the first day
I know the sheets by the first date
We really made something
A miracle that most won't see
But it meant a lot to me
I don't get why you had to leave
[Refrain]
I should've called by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days

[Verse 3]
All my friends say, "fuck you"
But I can't even help but love you
And even though you run me out dry
I still think you're a decent guy, why?

[Instrumental Break]

[Refrain]
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days
I should've called him by his last name
It's been seven weeks and three days, days
