My dentist (and also in my Stake presidency) turned out to have a 2nd wife nobody knew about.. including his 1st wife. Somehow he talked her out of divorce... now he lives in a new city/area, and #2 lives a few houses down.
I have another neighbor whose wife found out he was cooking meth in one of his dental offices. She divorced him, but he ended up ODing in her (their) house while she was away with the kids on vacation.
Dentists are the worst.
