Banana Yoshimoto said this quote
“ I suppose that's the reason I believe that as long as there is someone in charge of the household, someone who can maintain order among its members, someone who is clearly mature and established as a person, someone, in other words, like my mother, then eventually all who live under the same roof, despite blood ties or lineage, will at one point become family. Such a simple idea, but one that took a while for me to catch on to.Oh, and another thing.If the same people don't spend enough time in a home, even if they are connected by blood, their bonds will slowly fade away like a familiar landscape. ”
