Strangely, during the first lockdown, when I (a DBA, mind) was furloughed (but not for long - they realised their mistake quickly enough) I went looking for things to do: Places I might be able to volunteer to help.
As it happens, certain organisations were recruiting volunteers to help with the pandemic. I got lucky, and was accepted, and from there I got to volunteer for a program that's kept me busy most weekends this year (more if I have holiday - can't really go anywhere so... that's another shift signed up for!).
Probably the best part of the volunteering is meeting new people, chatting to them and getting them laughing (can't say they're smiling as masks tend to hide that bit), and people seem happy to socialise a little, even if they are there to get vaccinated. It's also quite the experience being around professional nurses and doctors, mixed in with the other volunteers: They're a remarkably friendly, welcoming and overall nice group.
It's this side that people overlook normally - it's only when you're there, standing along side them and taking a little bit of the pressure away that it's all that obvious. Well worth the time, just for that, but knowing you're helping others: That's the icing on the cake.
