I was surprised to learn that something I said in a voicemail message to a friend was common knowledge to the recipient's children, ages 20 and 17.
When I asked about it, my friend shrugged and said, "Meh, my kids access my voicemail and listen to a lot of my messages. They don't listen to each and every one of them, but they did happen to hear that one. I don't really mind, I don't keep anything from them."
If you have both voicemail and children, do your children have your password? If so, does it matter what their ages are, minors or adults?
