First impressions are so interesting! Especially since we are multi-faceted humans, but, for some reason, people like to categorize other people really fast.
I used to work in a male-dominated work place and I showed a (male) coworker a picture of myself in a fancy dress. Their response was, “whoa! You look like a girl!” To which I laughed and reminded them that, I was, in fact, a girl but they had barely interacted with me outside of work, mainly seeing me in our gender neutral work uniform, and me with no makeup etc. It was (and still is) really funny to me.
