"Luka" is a song dealing with the issue of child abuse. Written and recorded by Suzanne Vega, released as a single in 1987, it was her highest-charting hit.

My name is Luka
I live on the second floor
I live upstairs from you
Yes I think you've seen me before

If you hear something late at night
Some kind of trouble, some kind of fight

Just don't ask me what it was
Just don't ask me what it was
Just don't ask me what it was

I think it's 'cause I'm clumsy
I try not to talk too loud
Maybe it's because I'm crazy
I try not to act too proud

They only hit until you cry
After that you don't ask why

You just don't argue anymore
You just don't argue anymore
You just don't argue anymore

Yes I think I'm okay
I walked into the door again
If you ask that's what I'll say
It's not your business anyway

I guess I'd like to be alone
With nothing broken, nothing thrown

Just don't ask me how I am
Just don't ask me how I am
Just don't ask me how I am

My name is Luka
I live on the second floor
I live upstairs from you
Yes I think you've seen me before

If you hear something late at night
Some kind of trouble, some kind of fight

Just don't ask me what it was
Just don't ask me what it was
Just don't ask me what it was

They only hit until you cry
After that you don't ask why

You just don't argue anymore
You just don't argue anymore
You just don't argue anymore

The song deals with the issue of child abuse. On a 1987 Swedish television special, Vega revealed her inspiration for Luka:

"A few years ago, I used to see this group of children playing in front of my building, and there was one of them, whose name was Luka, who seemed a little bit distinctive from the other children. I always remembered his name, and I always remembered his face, and I didn't know much about him, but he just seemed set apart from these other children that I would see playing. And his character is what I based the song Luka on. In the song, the boy Luka is an abused child—in real life I don't think he was. I think he was just different".
