we were poor when i was younger.
real, not enough money for food poor.
we lived in crappy accomodation (temporary housing), with virtually no white goods. we had a cooker, when it worked, but no fridge (did have one, but it broke and couldn't replace it) and no washing machine.
we had a stint with no sheets (although it would have killed my mother to admit it to anyone) because we could not wash them.
it cost far too much at the launderette, and we did initially wash them in the bath, but then had
a) nowhere to dry them (we had no heating, and it would take days in an already damp (think mould growing all over ceiling/walls) house to dry them, and
b) not enough sheets as they were all wet.
so sometimes it is not about sheets not ocurring (although i can see how that situation would arise) - it really is about not being able to see a way around the problems that are currently facing you.
I do agree about all the money wasted on drink/cigerettes etc though.
my mum was a smoker a that point, and she gave up - simple as really. her choice was to smoke and have us all hungrier than we already were, or give up and at least try to have basic nutrition covered (and I really do mean basic - we usually had one meal a day, and a bit of toast as well if we were lucky)
later on, when we were a bit better off, she did re-start smoking, but for about 2 years she had one cigerette a day - she would really look forward to her cigerette just before she went to bed, it was her only pleasure for a long while.
