let’s Be honest: Even if we do not upset us, as before, the us imposed restrictions to limit the Covid-19-spread, really effective they are in everyday life for some time. The Parks are full, crowds of people come together to large demos, we meet again in coffee shops and Restaurants. The long-feared “second wave” so far, thank God, and probably under the influence of face masks and outdoor activities, however, failed to materialize. We hope that this will remain so.

If not, have your network prepared for the theoretically interested sociologists, but already an alternative strategy, so that we can avoid the next round of the radical avoidance of physical contacts. Alone necessary to it is, so you write currently in “Nature and Human Behaviour”, the networking of one’s own social contacts, and to behave accordingly. Specifically, they suggest three different strategies: first, one could restrict the social activities of the geographically close contacts. Secondly, make sure that the contact network is as close as possible to – that you meet only those with whom you share more contacts. And thirdly, you could just meet a selection of people you meet, anyway favorite, or most often and then stick to it.
