Playing Go Fish this afternoon, B was one card away from winning. He asked H if he had an 8 to which H responded Go Fish. B took a card from the deck, glanced at it briefly and exhaled loudly before saying "it's a 7, ah crap!". Clear as day. No mistaking it for another word. I do recognize that my response was not appropriate but I could not stop laughing. Of course, he joined in the laughter. I attempted, while wiping away tears and trying (unsuccessfully) to regain my composure, to let him know that crap is not a nice word and I did not want to hear him say that anymore. B's response: "Why do you say it then?".
