I was surprised how Germans could survive from the severe heat during the summer. It is really difficult to find a place with air conditioning. I expected at least every classroom and public transport such as buses and trains would have air conditioning, but most of them do not have it. Another thing I noticed was, I think the population is relatively well distributed throughout the German cities. It is common to see that the capital city of most countries is densely populated in a way that it is almost a disaster during a rush hour. But it is not the case in Berlin. It is also interesting to see that most people, at least in Berlin, speak English, which makes me able to communicate with them. I wish we also have friendly and safe beer festivals back home.
