For a bit of fun, have you ever heard a conversation or seen an exchange of messages that you're not supposed to but you can't help tuning into?
About a year ago I was next to an older guy on the tube who was typing out a furious email, presumably to an adult child, along the lines of 'Your grandfather would be ashamed, the businesses of [Family Name] has to be passed on....' and things along those lines. I just caught a glance of it and was transfixed. Serious family melodrama! The whole tone of it was like something from a vintage TV series, I honestly didn't think anyone actually talked (typed?) like that anymore.
