It wasn't a friend of any description. It was a fellow from Qwest [the leading phone company hereabouts], there to install the new phone line.
After a good fifteen minutes of straightening things out, much of it him on his company cellphone (on hold), it was determined that it was in fact not our apartment, but the one upstairs, and it had somehow gotten a typo on his job sheet.
I was much amused (secretly) to be referred to as "the lady". I guess I'm still used to being a girl.
