Sticky Fingers....................I Tell You #1

Ok, If you said she should rat out the person in question you were right....
AND wrong. Because according to the rules of family, unless of course, she was stealing from yours, let's assume not, since nothing was said in the letter, you can go either way on this, it doesn't make any real difference to anyone but you. So you could just decide to MYOB, who asked you, you don't know the whole story, why get involved, let it be. Or you can confront directly and say, I know what you're up to quit it or I'm turning you in I don't recommend this, too complicated, and really namby pamby. Besides you can't talk people into being honest. Or if you bring in the heat, you can either play dumb when people wonder who called the gendarmes or say directly I called the cops, she's a disgrace bringing up my taxes. All of these options are equally fine: do whatever lets you sleep at night.
