I wonder if they're celebrating the election result? (Or maybe some people just want to spread positive feelings, but that seems less likely to me?)
Presumably people aren't experiencing joy from the pandemic itself.
Some people like this lifestyle and are enjoying working from home and not having social commitments anymore.
Yeah, people who are not directly affected by the virus yet got some changes on their routine (no long commutes, more time with family) positively seem to be quite welcoming the changes
