If I saw a swear word I won't read or buy a book because as a teacher I cannot afford to be reminded of swear words so that they spring into my mind and out of my mouth when I drop a pencil.
I also don't want to recommend such a book. Why?
I don't want to have to explain swear words to pupils.
Nor do I want to have pupils going home and telling their parents, the teacher taught me this word.
