Wow...I remember everything mentioned here! I guess my grandkids are right...I'm old!
The only thing I can add that I haven't seen mentioned are phones with a dial & phones without a dial. We had to push the little lever up and down a couple times to get the operators attention then told her which number (only 3 digits!) that we wanted. Just like living in Mayberry with Barney and Opie.
My friends parents (almost 90...) still have a rotary phone on their dining room wall. Their great grandkids don't know how to use it. lol.
