I have never heard anything like this before, that most Germans prefer speaking English to communicate with each other. We have our language and we are proud of it. We love it.

Even though there are a couple of anglicisms used in our language I've never heard of anyone using English for communicating with friends, family, colleagues etc. As to me the only reason for talking in English is to talk with non German speakers.

Of course, nowadays English is taught at school in Germany so every and each younger person should be able to communicate quite well in English….. However, there is still quite a significant proportion of (often a bit older) people who have never had a chance to learn English or just have never practised their English after leaving school. I would recommend to learn some German basics at least if you intend to spend some time in Germany. Please don’t expect that you can rely on English all the time …. And yes, I have never witnessed native Germans speaking English in their daily communication …. Good luck with your German studies. Regards, Paul
