This is less surprising than it probably should be:
Throwaway. I’ll try to keep it to the point. Basically, my fiance and I are getting married soon, in about 4 months. Our families are all going to be there, including all of my extended family from around the country.
My sibling (this is new to me so it’s hard to imagine them as my sister when I’ve always known them as my brother) is also flying in to see me. Well they were going to at least.
We grew up pretty close and usually share everything with each other. The other day, they called me and told me they were identifying as a woman, and wanted to be called Stella. I was shocked and still am honestly, but I love them regardless.
