Like America, culture varies in Germany even from City to city in slight ways, for example in some cities I’ve been told people are slightly more friendly and more likely to smile at you while they walk by but in other cities or states you would get weird looks. Germans are also a lot more quieter than Americans. Multiple times I’ve heard from my partner that others were saying I was being too loud even though for me I was simply talking to somebody else but the Germans would compare my normal talking to almost shouting. Germans with their quietness, I think, tend to be more shy and non-confrontational so if you are doing something wrong they won’t do anything but silently judge you, which I have to say may have happened to me multiple times at least. The other thing is because there are so many cities and Germany is ultimately a smaller country than America, the big houses here would be considered small houses in America. Lots of people also live in apartment because of the lack of space. Germans are also more concerned with the environment compared to Americans. Lots of measures are in place to make an effort such as gas that is roughly double the price of ours and a cost for plastic bags when at the register. There is also something called Pfand where you spend 25 cents or so extra for reusable bottles so that you can return those bottles for the 25 cents back. Because of the money you can get for reusable bottles people that may need the money will take the bottles if they find any on the street.
