LOL...I will interrupt pcmaster's kissing lessons for a second and say it's quite ironic he has that quote printed on every one of his posts, "Doubt kills more dreams than failure ever will" and he is telling you forget about your dream...funny you pointed it out. Touché.
You suggest she learn on other boys, that she feels nothing about? And what exactly will she learn...to be with someone who she feels nothing for. This is the best way for her to learn, to go after something seemingly impossible, someone who makes her feel higher emotions.
That's living. Have you heard the quote "It's not the destination, but the journey that counts"? Look at all the positive that's coming out of this, it makes her dream, it makes her go after something
very hard to attain and it's not stopping her, it makes her be artistic, want to learn another language. She will learn a lot from this whatever the outcome.
A dream is not as impossible as it may seem, if it's not impossible to truly believe in that dream.
