I had an appointment at a financial institution yesterday.
Dear People With Offices With Doors: If the door is open, people sitting right outside can hear you complaining that you're very busy and who set up this appointment anyway???
Also, if the client has short hair, but is named Margaret? Chances are the client should not be addressed as "Mister."
I've always had short hair, so this wasn't the first time I've been mistaken for the male of the species.
I suspect that's one reason why I have no qualms writing from a male POV.
I also suspect I don't find it writing from a male POV an issue because I write historicals. All my characters have different world views and perspectives than I do, regardless of gender, so I'm making a major creative leap whatever character's POV I'm in.
Other writers, I'm curious -- do you think about gender differences a lot when you write?
