A few years ago, one of the mailing lists advertised a foundations talk he
was to give at the Harvard math department. I flew out to Boston and snuck
in, figuring the Harvard people would assume I was MIT and conversely. I
was found-out, though, as people were filing out after his talk; of course
everyone knows everyone else.

I knew his work from my days as a geometer. It was the sort of thing you
see in grad school and it impresses its beauty upon you forever. I came out
because I'd heard this and that about HoTT and it seemed like a good
opportunity to peek into that world. He seemed surprised that someone not
in-the-know would make the trip. We talked for a bit. He was generous with
his time in a way that struck me as incredibly humble. To the extent that
mathematicians have fans, he was good to his.
