Is lying.
three times a day
I work with a lot of people. If I asked each of them how their weekend was, I would be asking it a lot more than three times and I'd get nothing done.
No one is asking them to change or put a mask on all day
Telling someone to do something differently to how they would choose to do it is the definition of asking them to change, and it requires them to put on a mask. Being around any human, including my own family, requires me to mask.
If you ask me how my weekend was, I have to perform a mental calculus of "Is this person asking sincerely or insincerely? Can I trust them with an honest answer?" There's an inner flowchart I follow and it takes time.
What's telling is the number of senior people where I work who ask "how are you?", wait a beat whilst I start the flowchart, and then, before I've answered, plough on in with whatever they wanted to ask me about. They all instantly put themselves in the "do not trust" category by doing this, because their failure to wait for an answer tells me that the question is an insincere script they follow to make themselves look "nice" when they are not. If they were actually nice, they'd wait for my answer.
Now, my colleagues can collectively make me follow that inner flowchart several times per day to perform fake "niceness", or they can stick to work-related discussion. I would enormously prefer the latter.
