If someone sends you an ambiguous message, instead of letting it instigate yet another stretched-out volley of back-and-forth missives, reply, “Happy to help! Grab me during one of my upcoming office hours and we’ll figure out the details.”
Hate this kind of stuff. What if everyone does this? Then we're all f'd again. Seems real solution is to simply have enough bandwidth to be aailable to bang this kinda thing out when it comes up and is truly important, or ignore it if it isnt until later
