In 2020 it was a difficult year for many people. Shaking hands, a peck on the cheek suddenly became weird. For tactile people this would have been really difficult. Many teens are very tactile. You walk into a school playground in a high school you see girls hugging and guys fist pumping. Lots of physicality but then they were told, sorry no, 1.5 metres apart. You cannot even sit near each other in school assemblies.....
