Night to his day

In "Night to His Day" by Judith Lorber, she makes a point I can personally relate to. I remember a specific time when I was about 5 years old, my dad took me to a barbor shop and got my hair cut short. A few days later, I went into the girls bathroom and was waiting for a stall when a woman said to me "the boys bathroom is across the hall....oh! you have earrings! you are a girl, i apologize!"
So, as I was reading "Night to His Day", I understood where the author was coming from. I think gender is definetly expressed by dress and naming. For example, pink almost always represents girl and blue almost always represents boy.
My opinion on gender is that males and females are still very much so seperated. In the workforce, males are sometimes seen as more dominant. I think females have fought long and hard to get where they are in the workforce and are more than capable of holding high positions that some only see men in.
I don't think that seperation like this should exist at all. Women have just as much capabilty as men do in every field.
