I will omit details of names and the town involved.

The department was fighting a fairly large bale fire. A young fellow who was new was under my care until we could see how he worked out as a fire fighter. An hour into the fire he told me he had to 'use the facilities'. I told him to go behind the truck and 'empty the hose'. He said it was more than that. I told him to ask the farmer for the use of his toilet (and report back when he had 'finished his business'). He did. However, he spoke quietly with me and asked if I could keep the 'emergency' to myself, because he didn't want to be embarrassed in front of the guys. I gave him my solemn assurance. Next practice, he had a dozen adult diapers on his hook, in the pockets of his bunker gear, in his lid, and he received the nickname, "Depends". He has never forgotten that and we remain good friends.
