Today, my son said a sissy-cuss word. Actually, it was a unique three word combination (just because he likes to talk constantly whether it makes sense or not), the third word being this sissy-cuss word. It's a word that I confess to saying a time or two, although not in front of my son, so I asked him where he heard that word from.
"I just made it up," was his answer.
I have had him stop saying "made up" words in the past for that very reason. He has slipped before and said a "real" cuss word without knowing it. When he explained to me that he didn't know that this was a word he shouldn't say, I re-emphasized why I didn't want him just saying all kinds of words that he had never heard before.
He thought about this for a few seconds. Then he made a suggestion.
"How about if you give me a list of all the bad words you don't want me to say. I will look at the list so I can know them, but I won't say them," he vowed.
Hmmm.......Very sound reasoning to me..........
