Man, the younger generations can't fathom the concept of my office phone being a landline and being unable to send texts to it. Blows their minds.
Want to see their brain stop working, Tell them about a party line, phone booth, or a phone bank at a hotel or airport and see how they process that.
after they regain consciousness, invite them to lunch that only accepts cash and let them drive a manual transmission. It’s doesn’t get any better than that.
