Yeah that's a good idea, sometimes I was not sure which gender a person was, or I was surprised when I realized their gender. One thing though, what if a person is transgendered?? I guess they would just pick whichever gender they relate to most. Blah maybe that's a stupid thing to comment on, too picky maybe, but it's my mind because I met someone who was trans while in hospital, and this person considers themself both male and female.
