Cecelia Ahern said this quote
“ She got a sense that their time together was valuable, as though she needed to hold on to every minute as if it were their last. He was too good to be true, every moment spent with him magical, so much so that she presumed this couldn’t last forever. None of her good feelings had lasted forever, none of the people who lightened her life managed to stay. Going by her previous luck, from pure fear of not wanting to lose something so special, she was just waiting for the day he would leave. Whoever he was, he was healing her, he was teaching her to smile, teaching her to laugh, and she wondered what she could teach him. ”
