When I was still a baby, they moved houses and made sure there was wiring for a second phone line to the room which was going to be my bedroom, on the theory that one day I would grow up to be a teenage girl who never got off the phone. When I found out, I made total fun of them for it, being a typical asocial autism-spectrum kid who didn't really have friends and certainly didn't talk to them on the phone. We moved again when I was fifteen and this time they didn't bother.
Then senior year hit and a certain somebody started calling nonstop. I took the calls in their study... for hours... upon hours....
Course anymore I don't go near a phone if I can help it. Teenage hormones do very strange things to a person's brain.
