I would tell her how cool she is and that her music is great and so on :) cause i really like her :) and I would congratulate her because she has a great and talented husband and two cute kids and I would ask her for an autograph and if she could take me home with her to see johnny but i guess she would say no so i would give her my adress and would ask if johnny could send me an autograph too :)
I would ask her for an autograph or for a photograph :) Maybe i would also say something like "How's Johnny?" but nothing more 'cause I would maybe make her feel like we only care about Johnny n' not for her and that would be awful ='/
I would ask her to take me home with her...to see Johnny...or i would ask her telephone number or Johnny's number...because i don't want to loose the contact with Johnny LOL!!!So one day i could meet Johnny!This is my opinion...i would do everything to not lose the contact with Johnny...this is the only thing that interest me!!!!
