The other day something happened, can't remember what, but I said, "Oh crap." "Mom," my 8-year old son said, "you're not supposed to say that." Well, it was better than what I really wanted to say. While attending a Christian boarding school, I knew that I would have to curb the language, no four letter words here. But what I didn't know was that I was also not allowed to say shoot, darn or oh my goodness. These are minced oaths-words based on profanity, but changed to make them less profane. Didn't know that expression until I was told at school.
I still say words I shouldn't, like crap-four letter word, minced, chopped and pureed.
