Do I give him the letter?

My husband’s crazy mother, whom he doesn’t talk to, doesn’t want to hear from, and pretty much tries to forget exists, sent him a letter in the mail today.

It was one of her usual rants : “The rich are evil, the poor are poor because they don’t trust Jesus, the country is in a good place (What?) but in 30 years there’s going to be a recession (uh…huh…), you should really talk to your father more (we… do.) blah blah blah… ” Insert some random advice on business practices (she’s never had a job. Ever.) and some “Jesus loves you” crap, and this time throw in a couple of pamphlets for her church (which is in Illinois. We’re in Florida.)

I know it’s going to piss him off. I’ll have to listen to him rant for a week and overanalyze every screwy comment.

Can I really get away with not letting him know it came? or am I morally obligated to give him his mail? does it count as lying to him if I don’t?
