My sister won’t speak to me because I taught her daughter a naughty word. I was playing Scrabble with my 8-year-old niece, who is very smart. She always kills me when we play and it’s kind of embarrassing for me. But this one game was close. I had the opportunity to play all my letters to spell “fellatio” ensuring I’d win the game. I thought a bit about whether I should play this word or just lose graciously. Pride got the better of me and I played the word. My niece didn’t believe it was a word and looked it up in the dictionary. This lead to numerous questions about sex that I wasn’t prepared for. So I told her to ask her mother. When my sister found out what I’d done she hit the ceiling. She was furious at me that I’d taught her this word. Now she won’t speak with me. I’ve considered apologizing but I don’t think I did anything wrong. She would have learned the word eventually anyway. When I was a kid, I learned far worse words younger than that.
