Stop in for a cup of coffee

And most people under 20 would not know what that perk pot is.
Last summer, the 13 year old grandson went with us to a doctor's appointment.
In the corner, on a small table, was an old (1960-70's) dial phone. It was on display.
He walked over looked at it and asked me what it was.
I told him a telephone, and the puzzled look on his face.
I showed him how it worked and explained you walked as long as the cord allowed.
Then I started naming off the things we didn't have growing up, microwave ovens, computers, cell phones, color tv, cable (three channels on a good day), video games, etc..
It prompted a long discussion all the way home.
