It had already been determined that while they were growing up, the two of them were like adhesive, as defined by Seth Go. Since they had not met each other until they were in the second grade, it was too late for them to live in the childhood crushes that toddlers who grow up together often have.
By the time they were in second or third grade, the girls would have already figured out that boys have cooties, and boys would do their best to stay away from the girls. While it was certainly all right for the two of them to hang out constantly outside and during school, in no way would they have deemed themselves ‘romantically’ involved.
If they had met a few years earlier, perhaps when they were two, and then grew up constantly next to each other for the next few years, they could have lived in that childish illusion of growing up together.
Christina Sun could have proclaimed to her mother at some point, “Mommy! My last name is Go!” and happily went on her way. And after a Halloween (or rather, Harvest Festival) event at church, she would have told her mother about how the boy, Seth Go, had claimed that he loved her.
“And what was your answer?” her mother would have replied, acting nonchalant, but really trying to keep from grinning.
“I told him that I love him too.” The little girl would have been smiling, not thinking anything more of her statement other than that she would be with her best friend forever and that nothing would change. Not one day from now. Not in one week, nor a year. Perhaps not in ten years, or even a century (not that they knew what that word meant. Though Seth might have known what that meant, due to his relatively high thirst for knowledge and vocabulary—like ‘adhesive’).
And if this did indeed happen, the mother would have ruffled her daughter’s hair and smiled to herself at her little child’s blissfully ignorant proclamations of love. What she wouldn't give to be a child again.
