My daughter has school friends and gymnastics friends as well as a couple other sets of friends. As an adult have different types of friends. I have friends I go hiking with and friends who wouldn’t have any desire to hike.
It is actual said to be a good way to “bully proof” kids and is very healthy. By having several sets of friends and interests if one particular part of their world is not going well, it’s not their “whole” world. The other sets of friends and interests provide a safe place.
She too excels in PE. Routinely even beating the boys in challenges. There is no need to discuss her gymnastics with her teacher.
When kids from school are doing gymnastics at recess or a party, she doesn’t. When I ask her why. She is like Mom, they don’t do gym they way I do gym. I don’t need to do that. I go to gym for that. She really doesn’t like to stand out, she doesn’t need the external validation, she likes to just be one of the kids.
And she doesn’t talk about gym or meets with her non gym friends. First they don’t get it. And second those friends give her a place to not be “all gymnastics”. When she wants to talk gymnastics she goes to her gymnastics friends. They get it. She had a doctors visit to follow up on her injury. The first folks she told and messaged pictures to were her team. They get it.
