I've always had this interest in sibling relationships because I don't have any siblings. I'm completely a product of the one-child policy in China, so I always kind of wished that I had an older brother or a younger brother or sister just to have that bond, so I find myself constantly writing about that relationship.
Writing the first draft of a new story is incredibly difficult for me. I will happily do revisions, because once I can see the words on the page, I can go about ripping them up and moving scenes around. A blank page, though? Terrifying. I'm always angsty when I'm working my way through a first draft.
