I'm in my early 30s and remember when "pulse" rotary phones were still common.
I was recently talking with some "early 20 somethings" about phones. They were getting nostalgic about corded home phones and "brick phones"...
I made a circular motion with my index finger several times while making the sound of a rotary pulse phone "shhhkkt-tk-tk-tk-tk, shhhhkt-tk-tk-tk-tk-tk, shhhhhkt-tk-tk-tk-tk-tk-tk, etc.." and asked them "what am I doing?"...
...not a single one of them knew what that was.
