If I have daughters, I’ll have to be realistic – it’s not going to be like: “You can’t have a boyfriend.” If you lock your daughter in the basement she’ll sleep with everything that moves. You have to explain that you want to share that with someone special. The only thing you can do is teach what you know and hope that will make them a good person.
When that kind of stuff happens, especially when you’ve never had anything, you don’t really even know what it is.
Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws.
