BTW. Show anyone born in 80's & later a rotary phone. See the looks you get as they can't figure out how to call someone,lol
Eh, I would late 80's or 90's. I was born mid 80's (hence the tag...) and had plenty of experience with rotaries. God I hated my one friend who's number ended in ***-***-0990. Took 15 minutes to dial!

Then we got to the modern science fiction tool called "the overhead projector".
God we used to screw with those things all the time. A quick half turn of the bulb and out it went.
