Do any of you know how people did laundry 100 years ago? A woman (usually) would fill a tub with water, add soap, toss in some dirty clothes and rub the soap through them. Every so often they'd take something out of the water and look at it to see if it was clean yet.

There was an expression at the time "If it's doubtful, it's dirty". This meant that if they couldn't tell right away that the shirt or whatever was clean--if they had to look at it again and think about it--it wasn't clean yet and they had to scrub it some more.

"If it's doubtful, it's dirty" is a useful expression, and not just with laundry either. Think about it. If you're not sure if you should do or say something, if you're wondering if it's the wrong thing to do, there's a very good chance that it is indeed wrong and that you shouldn't do it. At the very least you should think it through.

At these times you might want to remember that other phrase: "Run the Twelve" and set your idea against the ideals of the Scout Law.
