When a child asked me recently, what I was, I simply replied 'Alien' - why try to stick a label on it, and use one of the designed pronouns, that would be equally confusing so I stuck with something she would understand. In reality it's how I feel - alien and alienated. Having only,(relatively), recently worked out how much of my thinking is feminine, and developed an understanding of what makes me dysphoric (mis-understanding of my feminine behaviours - I react as female in the main), it fits as the stranger in familiar lands.
