I have no desire to ride public transportation an hour each way to and from the office with random people, then queue up for the elevator bank to take a 35-floor ride with at least one other person who I probably don't even know and could be sick.
I have no desire to be in an enclosed office with any number of people who come into work possibly sick, whether unwittingly or because they fear for their jobs. With exactly zero windows that can be opened in the entire office.
I don't need the interaction. I miss a couple of people, but I'm quite alright without seeing them and only speaking to them on the phone once in a while. I have my wife and kids here with me, I do a weekly virtual happy hour on Wednesdays with some professional friends, and I keep in touch with family.
Personally, I like being healthy. I'll happily go back to the office when there's a reliable vaccine. Till then, if you want to return to the petri dish, have fun with that.
