Two that my Gran told me and to this day, I follow:
1) "Never steal anything small. If you are going to steal, make sure it is SO huge, that you never have to steal again."
2) "If you are in a stranger's home and you see a penny on the floor, add another one to keep it company."
Although they may seem like odd choices of advice, I immediately grasped what she was saying to me. In the first, one, what I understood it to mean, is 'Don't get messed up with something small because it will ruin your reputation. And if you're so conceited to think of stealing, make sure you do a SHAWSHANK REDEMPTION theft, so you're set for life." So far, all Prison Wardens have escaped the wrath of Lambikins.
With #2, I'm guessing that because she was viewed as an immigrant (half Finnish/half Native American) she and her family were viewed as the "Usual Suspects" if a theft occurred. So, rather than pick up the penny and pocket it, only to be accused of 'theft', add a penny, thereby dispelling any possibility of being labled a thief.
(you have NO idea how many pennies I've gone through in my life!)
