I met her once, back when she was just under-secretary for something or other. I had to help round up some interns to fill seats because nobody had showed up to hear her speak.
I edited her speech transcript for publication and it was OK but not particularly impressive, either. Not the worst I've seen, far from the best. Other than that we exchanged pleasantries but didn't really have a conversation. But I believe those accounts.
I generally avoid snapping selfies with politicians, it's kind of a cringe thing to do if you're meeting them in a work context and they're not, like, the president. Which is not an invite I'll be getting. But if I'd known she was a future PM, I probably would have. She still counts!
