You mentioned typewriters. I remember once trying to define a keyboard to a teen, and I’d said “the part of the computer that looks like a typewriter.” To which he responded, “What’s a typewriter?”
There’s nothing like the young ones to make us feel old! “When you were born, did they have cars yet?”
