MIL - mean of pocket, mean of spirit. Just a few examples:
On holiday getting fish and chips from a local put - I suggested a g&t while we waited - "that's very extravagant".
SILs remember being hungry as children.
Everything is compared and considered and sometimes the item she doesn't like as much but which costs £5 less is bought.
When her mother died she couldn't travel straight away to be with her father because she couldn't book an Apex ticket.
For DS's first birthday, she waited for the sales to start (his birthday is on Xmas day).
FIL used to keep a petrol/mileage log book.
Every time she sees me she wants to know what something new costs.
I am deeply extravagant in her eyes - she is deeply mean and miserable in mine.
If this was all because she was hard up and on a tight budget I could understand it. But she was a deputy head and fil was a chief engineer. When FIL died, he left he left her £1 million not including the house and she pays top rate tax on her pension and investment income.
Oh yes, and just remembered, "she's never had a 99 with a flake in it because they are so expensive and she remembers wanting one so much when she was growing up". DH and the SILs remember sharing a bloody cornet.
