That having been said, there are times when a curse word might actually be appropriate.* These are few and far between, but they do exist. For example, if a friend just lost his job, you wouldn't want to respond with this: "Gosh darn, friend. That situation is certainly unsavory."
* I got cursed at by the most delightful little old lady last Monday. We hung a screen porch for Miss Barbara and she was displeased with our work, describing it with a certain profane synonym for poopy.** She was; however, pleased with the fact that I fixed her Nissan and fully winterized a birdhouse.
** It was a fair assessment.
I once met a man who used the F-word as an adverb. I'm fairly certain he was entirely unaware that an adverb was a thing. It was that kind of cursing - every sentence kind of cursing - that communicates very little. The word had lost its shock value and instead just made him look unintelligent. If you asked this guy what television show he was watching, he might say: "American *&$%ing Gladiators." It was terribly unfortunate and horribly inappropriate.
I mention all of that because I want to show you what happened to my house while I was on a mission trip:

Damn.
