The epidemic affects many areas of life. I noticed that relations beetwen the Portugese people changed a lot. When I arrived in Portugal i was that everyone is very open to each other. Even if someone doesn’t know you, he greeted you with two kisses on the cheeks.
Now, in connection with the coronavirus situation people limited direct contact. They gave up greeting kisses and keep their distance in shops and other public places. This is responsible behavior and adapting to the situation on the world. I think it’s just a temporary change in habits and everything will be back to normal.
