Bucket Residence, Lady of the House Speaking

My desk at work is right by the phone, so when it rings, I’m usually the one who answers it. It’s not like I want to answer it (it’s never for me), but I’m the one who sits closest to it, so it makes sense. Right? Only, there’s a woman who, every time I stand up to answer the phone, asks me “Are you expecting a call?” Um, no (remember, it’s never for me). Perhaps I should just sit on my lazy ass and wait until someone else answers it? That wouldn’t work, though, because no one else, including the Ms. Nosy Parker, will actually get up and answer the damned thing. So, why does she keep asking me if I’m expecting a call? Is there some reason why that information would be helpful to her?
