My youngest child is very caffeine sensitive and she would talk non stop any time she had a little caffeine. When she was around 4, she had a Mountain Dew by mistake. The phone rang and it was a solicitor. We put the kiddo on the phone. 45 minutes later she was still telling him about her day at preschool. I’m really surprised that the caller didn’t give up earlier than that. Yes, we were listening to her end, so she didn’t give out private information, not that a 4 year old know much private info.
