He fell in love with me,
then I fell in love with you
And now I am watching you
follow her out the door
Of my house,
and it feels so mean
I didn't know you'd moved
on to another heart
While I was picking mine up
with its broken parts
I did it to him,
you did it to me
She'll do it to you
'cause we're 23 years old
And that's what we do
when we're 23

And I still remember
watching you in November
Like a Hollywood movie
on the silver screen
And you looked so good in 2-D
That I fell blindly for you
like he'd fallen for me
And I recognized the same look
in your eye yesterday
As you watched her
through your camera
with the split-second delay
I did it to him, you did it to me
You're next on the list
'cause she's 23 years old
And that's what we do when we're 23

And I wouldn't take it back
'cause now I know more about me
But I should've had a laugh earlier
'cause it's pretty silly
How we slide along the winning edge
and the losing edge and the middle
And we dance around and poke ourselves
on this love triangle
I did it to him, you did it to me
She's doing it to you,
we should start dating people
that are 30 at least
'Cause that's what we do
when we're 23 years old
And that's only half
of the stupid stuff
we do when we're 23 years old
And that's what we do when we're 23
