Here in the UK you may only meet other people for exercise purposes, outside. No visiting each other's homes. It's been this way in most parts of the country for months. Same in Ireland
In France there is a curfew from 8pm-6am and restaurants cannot open. There have been rules preventing meeting others at home, can't tell if they're active right now.
In Germany one person not of that household may visit another household, but only one. This is also true in Belgium.
Some areas of Spain are not allowing meeting in others homes at all.
So ... YMMV.
I was sitting in the park in a riverbank the other day, cops patrolled and asked people where they lived. Whoever you're with must live in the same household as you, and you may not be more than a km from home. I didn't see anyone get fined (although I believe they have the discretion to do so) but I saw some groups of friends be dispersed by the police.
Not here you can't.
We are not supposed to go outside for anything other than food / exercise and no meeting people from other houses.
People have been fined for going out walks because they didn't go to the closest park to their house.
Also, I don’t know where you live, but I think in most places on earth you can legally have dinner with a small amount of friends, without some “influential” person giving you permission.
