Not that this happens, but I think it is because everything about my body language has changed over time. If you are a trans person this is mandatory because you cannot allow the world to eat you alive.
You need to be kind, loving and polite but also fierce and be ready to signal that you aren't going to be intimidated by anyone. It has to stem from your pores and cannot be faked.
Until this happens within yourself you will not fit properly into a world full of all kinds of individuals some of which don't care for your existence. Your job is to find your center and, in plain colloquial terms, not give a "rat's ass".
So find that center and stay there. You will see what a huge difference it makes.
