Very true, Mark. I've been in the business (first responder, both law enforcement and fire/rescue) for north of 4-1/2 decades now. The lovely and gracious Mrs. B often expresses complete bewilderment over things I have had to deal with; she just can't comprehend how people can do such-and-such to other people. I remind her that she's looking at it from the perspective of a normal, well-adjusted, ethical, compassionate adult. Most of the people who do the unimaginable are anything but normal, well-adjusted, ethical, compassionate adults.
One of my favorite Hawai'ian terms is "Mahalo nui Loa." My good friend Gregg told me this account: It seems that many public trash receptacles in Hawai'i display the phrase "Mahalo nui Loa" on the hinged doors. Many tourists apparently assume the phrase means "Trash." In fact, it means "Thank You, Very Much." It gives him ~ and other Islanders ~ many chuckles.
I perverted it by telling Gregg I sometimes enjoy Trash-Talking, Mahalo nui Loa.
