Last gym, owner had a son with ridiculous talent, but the kid didn't do classes or team - just used the gym as an endless parkour course. Coaches learned not to admonish him for risking the safety of the gymnasts who were trying to train, as the owner didn't really tolerate anyone telling her kid what to do or not do.
Current gym has one coach's kid, really talented, and pushed like crazy. Looks like it's harder to be the coach's kid than any other kid. Doesn't seem to be much jealousy, just sympathy.
