blaine:
now and then I think of when we were together
like when you said you felt so happy you could die

cooper:
so when we found that we could not make sense
well you said that we would still be friends
but I'll admit that I was glad that it was over

both:
but you didn't have to cut me off
make out like it never happened and that we were nothing
and I don't even need your love
but you treat me like a stranger and that feels so rough
no you didn't have to stoop so low
have your friends collect your records and then change your number
i guess that I don't need that though
now you're just somebody that I used to know

blaine:
now and then I think of all the times you screwed me over
but had me believing it was always something that i'd done
but i don't wanna live that way
reading into every word you say
you said that you could let it go
and i wouldn't catch you hung up on somebody that you used to know

cooper:
but you didn't have to cut me off
make out like it never happened and that we were nothing
and I don't even need your love
but you treat me like a stranger and that feels so rough
and you didn't have to stoop so low
have your friends collect your records and then change your number
i guess that I don't need that though
now you're just somebody that I used to know

both:
somebody
(i used to know)
somebody
(now you're just somebody that I used to know)
(i used to know)
(that I used to know)
(i used to know)
somebody
