Second day at work was shockingly normal.
Got a number of knowing smiles, and at least one person congratulated me and asked if I was having “the surgery,”* to which I gently replied that whatever surgery I was having wasn’t anyone else’s business.
(My FAQ did touch on this, but obviously most in the office didn’t get the email it was attached to. I also printed a stack and put it on my desk, but it doesn’t look like many, or any, have been taken so far.)
* In my announcement email, I mentioned that I will be taking time off for renovations.
