right now it would be 'how to raise dogs and urchin's and preventing urchin's from using the new found button to wind mummy up which is the word FUCK' 
If my daughter had learned that word when she was the urchin's age, she would have said it a million times, so I was careful not to let her hear it. I don't know how I would have dealt with it at that age. Now, she feels like I lied to her by not teaching her what the curse words are, so I have been letting her hear a few. So far, she hasn't repeated them.
That reminds me of the time I learned the f word and then finding out stupid or idiot or shut up or duh weren't bad words so I thought fuck wasn't bad either. So I started to say it and my parents kept trying to punish me and I would keep on saying it until my mother threatened to slap my mouth. I said it in a restaurant and she slapped my mouth. I never said the word again. For a while.
Four years later, I learned the n word and mom tells me it's worse than the f word and she starts to go on and on about it and I was like "okay I know." She wanted to make sure I really understood it's truly a bad word, not a bad word as in not a nice word like stupid or dumb or idiot. She didn't want history to repeat itself except this time it be with the n word instead of the f word. Oh yeah I found out at the end of the school year from my old best friend that when her grandfather found out she and her cousin both taught me that word, they got in trouble by him. She told that story to another girl on the bus and she was sitting behind me. I'm guessing their grandfather knew if I learned that word, I would never stop saying it.
