And then it would finally connect, and your sibling would pick up the phone and start dialling....

Aaaaaaargh!

I remember way, way back in the days of dialup a very tech savvy friend had emailed me 20+ files, because I was the only one capable of stitching an image together. Took forever (days?) to download the files, and I had to redownload more than once due to roommates doing fun stuff like picking up the other phone line... (It was of his truck after hitting a moose.) Of course, I didn't get to see the image until he got home, I had a Hercules monitor, he had a fancy one that did actual graphics.
