Lol! I remember when my daughter was a young teen. Her friend was supposed to be dropped off at our place at 7:20 PM or 20 after. They were late and my daughter was kept running around looking out the windows saying, "'Where is she? She was supposed to be here at 20, she promised she would be here at 20...." go figure. I do know that she had a real hard time learning to tell time with an analog clock. We then realized that the only thing we had in the house (including our watches) were digital. lol
