This one actually came in when I first worked here and was still a receptionist (I’ve since worked my way up to Bookkeeper, in case that wasn’t apparent or I hadn’t mentioned it). I was so flabbergasted that she would just call up and ask (and specify, for children–not infants, not boys, but children!?) that it was awfully tough to keep a straight face. Obviously she’d mean to dial the doctor’s office (again, another one of those 1-digit oh-so-important differences) and not us, but this is probably my all-time wtf moment of wrong numbers at work!
