The next few days were rather uneventful. Fu Hao Xin was a quiet child who didn't know how to socialize, and following the likely demise of his parents, he had only become more quiet. Aunty Wu, on the other hand, being the adult, probably should have been the one to break the ice, but being the odd person she was, she didn't bother initiating any conversation either.
So, other than a few words here and there to tell Fu Hao Xin to move out of the way when Aunty Wu was sweeping, the conversation about Fu Hao Xin's smile was the last conversation they had.
