However, later, he and I were chatting with Becky about scheduling and he mentioned that his multiple medical conditions require time off for doctor's visits. He went on to tell us that he has some severe psychological issues that relate to problems he and his wife have had in the past that have resulted in multiple separations.
Neither Becky nor I blinked an eye at this, but soon after he left, we talked about it and Becky thinks those psychological issues COULD be related to his unique relationship with his wife (sister). Of course, this is all speculation, but based on the information we received.... seems like a possibility, no?
I do find it interesting that people are willing to share this kind of information with us, especially given the seemingly common perception that museum people are boring (and probably not exposed to drama regularly)!
