The pandemic has brought with it completely new dilemmas when it comes to social interaction.

The wisdom and etiquette expert Mats Danielsson says in SVT's Morgonstudion that a new way to show courtesy has been to say that you do not have corona if you happen to cough for another reason.

But he does not recommend teaching anyone who snorts on the bus. 

- We all know that it is difficult to educate others on the bus.

So in that situation, you only withdraw if possible.

Otherwise you have to try to turn around, he says.

There are some who find it difficult to signal that they do not want to be hugged, but there Mats Danielsson thinks that polite honesty is the best.

- It's just to say 'no thank you, right now I keep my distance, so we will take it in the future'.
