What part of no don't you understand?

Some people just can't take no for an answer. They think if they bug you long enough, you'll change your mind. You probably would, just to make them go away.

No, I can't work for you tomorrow, I'm busy. Yes, I have a life.

No, it can't wait till after 12, when work is over. I have things to do in the morning too.

No, I'm positive I can't do it.

No, I don't want to work for you.

No, I don't know what I'm doing next year, but I'm not working for you.

Because I don't want to.

Yes, I know you really need someone, but find someone else because I'm busy.

Yes, I'm really busy, and not trying to brush you off.

No, I don't know anyone else who can help you. (And if I did, I'd only give you their number if I didn't like them, and wanted to bug them.)

(Then you go for the sympathy card, and hope to G-d it works.)

I'm so sorry, I feel really bad that I can't help you out, but I have things to do. Maybe another time. (Not)

The biggest mistake you can make is giving out your phone number.
Solution: change your number. Or just put your phone on silent, and go back to sleep.

I said no. In this context, it means no. Which is not yes. It's the negitive form of yes. Which is no. No, no, no.
