The bananas thing, id never have known but i think i might have a reason why (assuming its not a joke) they invoke such deep feelings...
I used to work with a German, born in what became East Germany, was in the Hitler youth (you had no choice), emigrated to the US qfter the war, settled in the UK.
I once asked him, pre fall if the Berlin Wall....why does everything look so grey and dull there ? Why dont they just spend a few quid and paint things up a bit.
His answer was immediate...
When you cant even put food on your plate...you dont worry what colour the house is.
I suspect they knew a thing or two about hard living

Definitely tough times in many, many ways. With bananas and oranges as exotic to ordinary folks in at least one part of northern Europe in 1984, as they would have been in 1584, it says something about a society - and not good things. That said, there was a certain security and certainty about life, too, which became (still is) the subject of a type of nostalgia - there's even a specific term for it - ostalgie, or its anglicised equivalent, ostalgia.
Many in East Germany greatly resented certain aspects of reunification and felt short-changed by it, likening it to a colonial takeover. As one of a large number of professionals from Western Europe who were 'brought in' in the short term to help upgrade all sorts of services, especially in Berlin, I can totally understand why they would've felt like that. Some of the Ossis would tell me they preferred by far to have Brits, Dutch, Scandis etc 'updating' and 'improving' stuff than to have their supposedly-fellow West Germans doing it, as we were, in the main, less arrogant and patronising than they claimed many West Germans were.
I had a flat in a building which had been modernised; all of us tenants were non-Ossis and of course we all had nice bathrooms, constant hot water, central heating, triple glazing etc etc yet next door was a building which had not been modernised - and in which people still lived with one cold tap and a toilet on every floor; I'm honestly surprised there wasn't more unrest. I always used to feel really bad walking past there and the smell of cheap disinfectant and damp that flowed out whenever a door was opened was something else.
The first, or perhaps it was the second, winter I was there, a decision was made to close the 'warming stations' which were scattered all over the city, we're all free now aren't we? Well that worked well - NOT - as about a dozen people died of the cold in the first bad storm of winter. Many people bemoaned the loss of the state-run, subsidised neighbourhood 'kantine' too; the meals might have been basic but they were hot, filling, cheap, served in the warm and dry and very convenient and sociable.
I've not been back and don't think I want to as it will have changed too much and I have a sort of 'ostalgie' too, for the way the new buds of freedom and change were only just showing above the surface when I was there. The local bakery still sold bread by the part-loaf, and the old signs for the Communist Party Investigations offices had not been taken down from the building kitty-corner to one I lived in; it won't be the same now!
