Ha, ha, ha, ha, ha! I couldn't even type that without laughing. As a native Northerner I know there's no such thing. It's not that Northerners don't believe in any of that, they are actively opposed to it. Witness the following:

"Good morning, sir, how can I help you?"

"Good morning? How do you know that? You some kind of expert on good or mornings? You got a college degree in it? What makes you think I need your help?'

"I was just being polite."

"Polite? What's that?"

Guy picks up his date. He gets in the car and starts it up. He fiddles with the radio. He looks over and sees the girl standing there. What? She helpless? Okay, so he reaches over and flips the door open. What's that dirty look for?

An old lady is crossing the street. She uses a walker. Now, I'm not saying she gets rundown. Come on. Maybe nudged a little bit or honked at, causing her to loose control of her bowels. That's about it.

Good manners in the North is asking before taking a slice of pizza from another table. You take it regardless of the answer but asking is considered good manners. Drinking the beer of the person sitting next to you when he goes to the restroom? Sure. He left it there didn't he? It would be flat when he got back anyway.

Offering a good-looking girl money to go back to your place isn't good manners even in the North. Offering an ugly girl money is. Heck, you aren't really going to give it to her anyway so what's the harm?

Making a rebuttal to the preacher is okay as long as you don't call him a, "dirty heathen." Offering a rebuttal to a funeral eulogy is okay if the deceased died owing you money. Just don't get too ugly about it.

Northerners invented the B.Y.O.B. thing. Yes, you are having a party and you guests are supplying the booze. If you are very well-mannered you will provide glasses and ice. Plastic cups are acceptable as is plastic ice cubes from your kid's play set.

Northerners came up with the idea of paying to dance with the bride. Well, why not just sell tickets and be done with it? Even the groom doesn't want to dance with some of these brides. Who wants to dance with a pregnant woman except her dad? He's happy.

Yard sales. Yep, a Northern idea. "One man's junk is another man's treasure." No, one man's junk is junk. Pay ten dollars for something that cost twenty in a store is a great deal. No warranty or refunds if it doesn't work, of course. You buy it without wondering why it's being sold if it did work
