Ok, so who are we going to invite to our dinner party?
Well, we have the Thompsons, the Greens, and the Andersons, about twelve people total.
Don't forget my friend Andy from the office. He has nothing to do on Friday, so I invited him over.
But that makes thirteen people! We can't have thirteen people for dinner on Friday!
Why can't we?
It's an old superstition. If we have thirteen people at the table, then it means bad luck. Can Andy bring a date?
I'm not sure. He just broke up with his girlfriend recently, and I don't think he's in the mood to start again so soon.
But we can't have thirteen for dinner!
I think you're making a mountain out of a molehill. It's only a superstition. It really doesn't mean anything.
Absolutely not! I refuse to have thirteen people for dinner on Friday!
Ok, ok. I'll ask my sister to come. That way we'll have fourteen for dinner.
That's better.
