The pandemic has changed a lot of peoples social distancing, especially in the workplace, where even being too close to someone can result in big bad juju… never mind touching them.
All it would take is one complaint, or threat of legal action, by a client to change a therapists entire mode of interacting with everyone they see. Much less threat of divorce by a spouse, a sick kid or relative with a compromised immune system at home, losing someone to the pandemic, or even just a wake-up moment of disapproval of one’s peers at a dinner party (You do WHAT?!? Are you trying to get reported, lose your license, or go to jail?!?)
Meaning, for my money, occams razor says 6.5 million dead people are the most likely source of the change.
Why later rather than earlier? Or no elbow bump dance, or shoe shazaam? Couldn’t say. Half my fam is in healthcare &/or research, so we switched to universal precautions and stripping naked in the garage (clothes in the machine, decontam shower before entering the house) as soon as it hit. A lot of people had to have something personal hit before they made changes.
Of course, that may not be the reason, it’s just the most common one, at present. No way to know for sure without asking the person themselves.
