So I have a handful of a three-year-old. I was walking past an electric fence with Maia the other day and I told her very seriously to not touch the electric fence. Bam! Her little hand went out and touched it. Thankfully, it was not on. The next day, we were at that same yard again, and the gardener told me that the fence was on. I explained to both of my kids what an electric fence was, being as graphic as I could. But the next day my daughter ran up to the fence and purposefully touched it. And that time, it was on. Hopefully the lesson is learned now.
