Best friends is probably hyperbole, but in a nice way. Like any other business, some relations are mostly transactional and sometimes you just come across people you like and sometimes you do have a chance to be friends with someone you wouldn't have talked to in the laundromat. People are interesting that way. I would take it as a compliment and laugh a little.

Unlike other businesses, people tell us their deepest, darkest secretes and live a whole life that they can't even talk about outside our dungeon walls. Sometimes we might forget, as normal and day-to-day it is for us, these are monumental moments for many of our clients and they share them with us. I quite like that bond and ability to be the one to see under the "dark veil."
