Alkaline Trio

I wrote the words to this song on the back of a photograph
Behind your back it goes
A little something like this is way to big to miss
I got a letter in the mail
The sender failed to let me know where
it came from
Opened it up and sure enough there we were
arm in arm (up in arms) again
I know it's small but my last calls been called a half an hour ago
I know it's late but do you think you could at least fix it for me
Then I'll go I'll go alone I swear
