My physical disposition is pretty well defined, but since where talking about the mental, it's much more complicated.
I would either classify myself as a Boy/Girl, or a indistinguishable gendered child. I don't identify with either the male or female expectations of gender nor do I view myself conforming to it outside of culture necessities, such as public bathrooms, changing rooms, and (arguably) gender exclusive attire.
As for why I define myself as a child, if the difference between adults and children mentality is defined by their knowledge, experiences, and wisdom, ect. Then I will never classify myself as an adult, not only can these vary tremendously from person to person, but are limitless in their quantity. In what way, would you, scale these and at what point, would you define, that they pass the thresholds into adulthood?
Side note, abstained from voting.
