Not food related, but definitely about mean behaviour...
My MiL was extremely mean, and not just with money.
Tea bags were used three times, and hung on a line to dry twice, no light bulb in the fridge, central heating only on for 'visitors' even if there were icicles inside the windows, 4ozs of mince to serve 3 of them, (I was never invited for a meal), only served tea as coffee was too 'expensive', I'm sure you get the idea...
Every Christmas we had to return the card they'd bought us for our first Christmas married, so that they could give it back to us again the following year! They went abroad every Christmas, and never bought presents beforehand, as they would buy everything after the event, in the sales. When DH had a bad back injury and was in traction for three weeks, they didn't visit him, ring to see now he was, or in any way show any concern at all for their only child. I phoned them once to tell them how he was doing, but MiL said she was watching Coronation Street, so I'd have to ring back.....I didn't bother!
The worst thing of all is that she never, ever, not even once cuddled our son! She was cold in the extreme, to the point of weirdness. She even told me once that she was angry that I'd 'stolen' her son away from her, as 'Now I have to do all my own vacuuming and ironing, he used to do it for me'! She was not in any way disabled, just lazy, cold and mean! Both she and FiL dressed for our wedding in clothes they'd had for years, and they didn't buy us a present either!
If they'd been really poor, maybe the money part would be understandable, but when she died it emerged that she had been squirrelling away cash from the housekeeping for 52 years and had three accounts which even FiL knew nothing about, worth £65,000!
Unfortunately FiL is much the same as her, never rings to have a chat with his son, only ever calls to say he wants something doing/getting/fixing. He's 85 now and as fit as a fiddle, but won't do anything for himself, DH has to do his gardening, decorating, shopping etc or he'll make his life hell!
I'd have told him to sling his hook many years ago, but DH can't see it, so we just don't discuss him and I avoid him whenever possible, which doesn't include Chistmas day unfortunately!
And the best thing about all this, he lives less than 2 miles from us!
He asked DH to check his bank statements a few weeks ago, he's sitting on roughly £450,000 and when our DS (his only grandchild) got married earlier this year, he bought them a present for £14-50!
So, when I say that when he's no longer with us, we shall hopefully be moving into his enormous detached bungalow, having wonderful holidays and paying off DS and DDiL's mortgage, I'm not being cruel and nasty, but I would like to see DH benefit in some way after the years of rotten treatment he had from his parents! I say 'hopefully' because I wouldn't put it past him to have left nothing to DH or DS in his will!
I really don't care about how badly they both treated me over the years, but I don't like seeing DH or DS getting dumped on from a great height!
