Once, Via woke up in the middle of the night and saw Mom standing outside August's room, listening to him sleep. Via thought she looked like a ghost or an angel. She tried to sneak back into her room without attracting Mom's notice, but she failed. Mom explained that August was fine, walked Via back to bed, and kissed her goodnight. Via wonders how many nights Mom has stood outside August's door, and wonders if Mom has ever stood outside her door.
Again, Via's wondering if Mom has ever watched her sleep shows that Via desperately wants to feel as though Mom loves and cares for her as much as Mom cares for August. This in turn suggests that Via's insistence that she's already independent is a way for her to cover up her longing for attention and care.
