I get some of the best fan mail!

Sometimes, I do get genuinely nice messages, like this one from a former student:

...he made a tremendous impact on me in the relatively short time we were in close association and I always appreciated his genuine friendliness and enthusiasm. Stacy, I'm pretty sure you're going to get a Twitter notification about this, so: thank you for the time we spent together during my undergrad. I might not be on the astronomy train anymore, but our class discussions about philosophy of science have stayed with me in a big way. You brought considerable texture to my worldview and never condescended. Thank you again.
