If I were the brother I would try to join a group (like this one only) with other teens who have a family member who is or has switched/transitioned. Honestly the best chance you have of him calling you she is if someone he respects who is the same age as him tells him "I didn't like doing it at first I called my brother my brother ever chance I could get but now I call her my sister out of respect because I realized that she would do it for me if I asked her to." If an adult told him this it would not give out the same effect. He needs to hear it from someone who is in his situation and who is under 16 years old.
For me personally I don't see the big deal about switching pronouns, I know it takes the average person about 9 months to stop having slip ups but honestly I believe switching pronouns is easier than quitting smoking, if people are having THAT much trouble with it, then it is not because they are forgetful it is because they don't care or they are stubbornly refusing to try. Usually after a women who changes her last name after marriage can expect everyone to know and use the new name within the first year, how is this any different? ? ? It is still a name change? I can see the parent who choose the name to be sad because well, I spent a lot of time and energy picking out my kid's names!!! but for everyone else F*** 'EM!!! Who gave them the right to name you? It's RESPECT people learn it! For the stupid disowning people out there I hate you too! "Oh your not my sister any more because you got a tattoo" F U "Oh you are not my son anymore because your gay" F U "Oh your not my parent anymore because you changed your gender" F U "Oh you are not my friend anymore because you got an abortion" F U
The only reason why teenagers don't show respect is because ADULTS don't show respect!!!
One half of me wants to be sympathetic and say, well it is hard on the brother too, he has feelings and thoughts just like everyone else, give him time -sure, let him know you still care -sure.
The other half of me whats to tell people stop whining! If you are 14 and the worst thing in your life is that your brother is now your sister then I'd love to be you! Try having a brother that raped you, try having a brother that died of cancer, try having a brother that went missing, try having a brother who has to live in a different country than you but not by choice. There is so much pain and suffering in this world, I believe people switch to make the suffering end not to cause more, why don't others see it this way?
Sorry for being so b*t**y -yes it's that time of the month for me to have no patience with people and tell them all to grow up!
