Lyrics:

Sir if you dont mind I'd rather be alone
From the moment I walked in tonight
You've been coming on
If I've told you once, I've told you twice
I'm just here to unwind
I'm not interested in romance
Or what you have in mind

(Chorus)
What part of 'No' don't you understand
To put it plain and simple
I'm not into one night stands
I'll be glad to explain it
If it's too hard to comprehend
What part of 'No' don't you understand

I appreciate the drink, and the rose was nice of you
I don't mean to be so mean
I don't think I'm getting through
Oh,I don't need no company, and I don't wanna dance
So what part of 'No' don't you understand

(Repeat chorus)

I'll be glad to explain it
If it's too hard to comprehend
What part of no don't you understand
What part of no don't you understand
