I never experienced a party line!
But our kitchen wall phone looked something like this. (Originally black, but newer one beige. Hey, I think that's our wallpaper, too!

)
Such a pain when a line was "busy", having to re-dial over and over... (I think originally we had 7 digit numbers but then we went to ten, to add the area code, when we ran out of numbers.)
Anyway, one day I was sitting on the kitchen table mindlessly talking to a friend. I had keys in my hand for some reason, I guess someone left them on the table. There was an electrical outlet on the wall right where I was sitting. (Ya, you know where this is going!) For some reason I thought it would be a good idea to stick a key in the outlet while I was talking... Ya, BOOM!

It exploded and I got shocked!

I think I screamed, and my friend was like, "What's going on?"!
It's amazing how phone technology has changed!
I was at a conference the other day where participants all used their smartphones to answer questions the lecturer was asking. (Several ways to do it, either by text or App.) As answers were submitted, they were projected onto the big screen. I hadn't seen that anywhere before, but we were all commenting at our table on how much times have changed!
