A few years ago, my wife toyed with the idea of sending this type of family newsletter to friends as a Christmas greeting.
Since I usually do all of the writing for her, she asked me to compose the newsletter. I wrote one similar to the second letter.
IIRC, my 14 year-old was in rehab and our baby was taken away by the state; I was getting back into the meth business and the wife was offering herself over the internet for shots of tequila.
She got the idea.
My husband and I played with that idea once, of writing something sarcastic and hilarious, but we never did.
