Even as a German, I sometimes struggle to connect with others for many of the reasons FirmwareBurner mentioned.
I made some good friends through a sports group I attend, which also organizes regular social events outside of training.
But aside from that, many so-called 'low-key social spaces' tend to feel like they're 'only for groups' Not because of any official rules, of course, although some places do advertise things like 'bring your friends', but in practice, you usually see people there in pre-formed groups. These aren’t necessarily close friends either, sometimes it's coworkers or people who already know each other through other contexts.
Those groups tend to stick together, and it's rare for outsiders to be included unless you already know someone who can introduce you.
