actually name changed for this , as it outs me,
My DH has twins for siblings as well as others, When his father did a bunk with one of the OW (he had affairs with almost everyone), he stripped down all the bank accounts, ran up debts, took out loans, maxed out the credit cards, leaving MiL with a large mortgage, the debts, and quite a few young children, and went half way round the world (we found out recently), and became totally un contractible.
The week after MiL had to deal with this, finding out hour by hour more and more, her MiL (incredibly wealthy) rang to announce she was going to visit for the twins's birthday,
She arrived and presented the twins with a puppy each, explained that the puppies were to help them get over the loss of their father, ignored the other children(DH included) then gave MiL a letter that contained a bill for all the money FiL had ever borrowed from her, and left.
She later wrote to my MiL to explain that she only had herself to blame as he was far too good for her, and she better make a better job of bringing up the children than she had of her marriage, and to threaten her for the money or lose the house.
I do hold this women partly responsible for, raising such a selfish git, helping to push MiL over the edge, making DH into a carer as a child, and when DH moved in I got two elderly massive dogs, with loads of problems who lived for years, the twins sensible lost interest in the puppies at the first signs of poo and wee.
and she is still alive, MiL really needed a MN in those days.
