i think it is hard for someone 7 years younger than her peers to to have a normal social life, at least with her peers. she's 7 years younger her interests, although she may be more mature than people her age, will still be a bit different to her older peers.plus the age factor that they can do certain things she can't so she will automatically be left out. i think the better way to go sociall would be to keep her going with the tennis and piano. tennis can be fun and social at the same time, plus she'll be around people her age. playing some social sport and keeping up with her friends from back when she was a bit younger would be better imo. course i'm not in her situation and never will be so it's always tough to give advice about things you haven't experienced yourself.
