I had a full-body coughing fit yesterday that I'm still sore from this morning - blargh. OTOH I feel much better today so I guess it worked to expel whatever demon virus I was possessed by.
I've found, annoyingly, that going into the office part-time makes it near impossible for me to be productive on WFH days. When I was at home full time I was able to engage Work Brain at my desk, but now that I've adjusted to being in-office most days it's much harder to convince myself that home office is a Work Brain Place.
