Wow. You're presuming a whole lot about their thoughts and motives. Do you read minds?They are still out there, that is, those people who are still terrified of Covid and wear masks everywhere. Every waking hour is spent in fear from Covid or climate change. And no, they were not really old or sickly, the opposite, they looked young and healthy. I felt sorry for them to be honest, looking at them in the same light I do as those who are scientologists or JW's going door to door selling their cult.
Maybe they just saw you coming.
