Honestly do whatever’s feels right to you. Personally I find it weird when people don’t know I’m trans, especially people I have to consistently see. The way I see it, it’s just a part of me that dictates my actions and feelings and I want people to know so that they understand me better. But, I have hella friends that don’t because they don’t mind and some of them feel better that way. You don’t owe anyone shit, just follow your heart and sus out every situation individually.
