A/N: This was a request from a fellow member in our group from either myself or my good friend Bev to write a parody based on this song. We decided to tackle it together in our first co-written work.
I was given her blessing to post her bit and as always I do not own any of the characters or story from the Harry Potter series. That belongs to JK Rowling (and co)

Somebody That I Used To Know

Legend: S = Severus (Written by Jess)
L = Lily (Written by Bev)

Setting: Marauders era, Snape outside Lily's common room

S:

I've been thinking about that time when we were younger

I never thought I'd be so happy I could cry
I called you out a witch, Lily

I was scared but you were there for me

But what I said out by the lake, can you forgive me?

S:

You started hanging out with Lupin, James and Sirius

His indignation in the end, you tried to pretend

That he was fine but it did not make sense

How could you hang with Potter and his friends?

When I always had to look over my shoulder

S:

But you didn't have to cut me off

Make out like it never happened and that we were nothing

Look, I don't even need to go

But you treat me like a stranger and I've had enough
L:

No, you didn't have to stoop so low

Make friends with my oppressors and then act all shady

You hurt me more than you can know

Now you're just somebody that I used to know

Now you're just somebody that I used to know

Now you're just somebody that I used to know

L:

Now and then I think of all the times I had you over

Your family was fighting but you didn't want to tell no one

But then you had to go and say

Something you cannot take away

You said you didn't mean it though

And I wouldn't catch you hanging out with blood purist bros

S:

But you didn't have to cut me off

Make out like it never happened and that we were nothing

Look, I don't even need to go

But you treat me like a stranger and I've had enough
L:

No, you didn't have to stoop so low

Make friends with my oppressors and then act all shady

You hurt me more than you can know

Now you're just somebody that I used to know

S: (Somebody)

L: I USED to know

S: (Somebody!)

L: Now you're just somebody that I used to know

S: (Somebody!)
L: I used to know

S: Somebody…

L: Now you're just somebody that I used to know

I used to know, that I used to know, I used to know somebody
