Some non-active hobbies for teen girls would be: reading (there are books about almost everything, so don't think that books are boring, because with the wide range of books today there's most likely something that fits your fancy), writing (you could write encouraging letters to your friends, set up a blog (although be careful not to give out too much information about yourself), write a book, write an article about something you enjoy doing), watch movies (although I'd advise dancing to the music in them if your wanting to watch them often, otherwise you might turn into a blob of a couch potato, and that wouldn't be nice), set up a website and make it a cool place for other teens girls to hang out.
As long as it stays nonactive, or dormant, it is fine.
Any.
Sure he can be.
KIA Soul Definitely. For a girl or a guy especially a teen.
Get a hobby.

Girly Teen Girl. P.S: I have no idea why they put Girly Teen Girl in that episode.

Niclel is better than Penny for a teen girl with rough roads.
