I live in Germany for over 15 years now and I'd like to share something about culture.
I've met this new team at work and literally everyone is great, I get along well with them and we even do things together such as Videogame-Nights once every two weeks, going out to dinner every month. I really like these guys.
There's this one guy with whom I get along really really well and he invited me to his house to meet his wife and family. And it was a simple invitation and nothing was said beyond that: come to my house and we'll drink coffee and talk.
I bought a cake and some other things and was prepared to sit and talk to people. That's what I did for about 30 minutes and it was really cool, he has a very cool and lovely family!
Just like out of the blue he jumps from his chair and says: "come on, I've got the bikes prepared for us. We're going to ride by the river!"! That was quite a surprise because we just left his family sitting there and went out to ride our bikes like we were running away together to start a new life elsewhere.
I wasn't upset at all because I do like riding bikes and he showed me some very nice places. It's just that our ideas of 'hanging out' are very, very, VERY different and I'd like to say I had a really good time doing this.
If this happens to you just go along with the flow and enjoy your ride/walk (because germans walk a lot, it's their 'thing') and enjoy the nature and the talk. #local source
