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
