Of course, this is not unusual for big cities where people have established their social circles and get on with their lives without paying too much attention to newcomers or showing eagerness to grow their social circle Even though one shouldn't expect to walk into a bar and be invited to a table to join a group of strangers, there are many opportunities to build a social circle, which will make life in Berlin more fulfilling. 

Germans are active people who like turning their leisure time into quality time with family and friends. Hence, there are so many leisure activities in Berlin to choose from that will also help you come together with other people under a common goal — whether it is winning an amateur football game, setting up a picnic at the park, or learning more about the city by taking part in a city tour. If you want more structure in your free time, you can sign up for a gym or club membership.

Your suggestions may include activities on neutral ground (e.g., drinks at the bar close to the office), dinner or brunch at a restaurant you have wanted to go to for a while, or an invitation to an event (e.g., a concert). Even though hosting at your place requires more effort and some preparation, it is an excellent way to create familiarity and offer the space for meaningful interactions on a more personal level. So, if you have the space and you don't mind putting together some easy snacks and filling the fridge with beverages, you can invite some of your new acquaintances over to your home. Taking the initiative is good. However, be mindful not to overdo it with invitations and suggestions, as people may get overwhelmed and start turning your invitations down.
