jumpandpop you could be describing DH's grandmother except that she doesn't claim benefits / pension credit.
She has wardrobes full of good-quality classic clothes, wouldn't dream of changing the furniture which was bought when DH's mum was young and really was built to last. Still lives in the large 3-bed she brought her family up in (paid for) and can heat and maintain it.
Good pension from the RAF, she served as did her late husband as well as other bits and pieces because she worked all her life.
She too goes to social clubs every day to three or four Churches a month in order to see all her friends but she doesn't spend anything really.
She reads and writes letters in her spare time, watches the news and listens to the radio. Until recently she had a gentleman friend who she provided a lot of care for - care his own children and grandchildren were very reluctant to give and to transfer to her 
She has the sort of inner resources we should all aspire to have and yes, it is a real pleasure for her to treat us every now and again.
But as DH says you don't raise three children during / immediately post-war without learning a thing or six about priorities and budgeting. My children and I am extremely fortunate to know her 
My parents are completely different, baby-boomers to whom aquiring things (thousands of CDs and DVDs they never use for example) and show-of-wealth (even when they didn't have the money) was paramount. They are manic about possessions and used endless credit all their lives.
They didn't even stop when they retired but blasted through the money they got through an equity-release scheme (which they don't even understand. They think they will pay just the money they borrowed back with no clue about compound interest) and my Mum bought a new Landrover at £300 per month for five years which was more or less her entire pension 
I like to think that DH and I, and our generation are going back to the old values
but luckily we haven't had the real grinding hardship her generation faced and faced head-on.
