If you saw her in these moments, you might think she was collecting her thoughts in order to go forward. But I see it another way: Her mind is being overwhelmed by two processes that must simultaneously proceed at full steam. One is to deal with and live in the present world. The other is to re-experience and mourn something that happened long ago. It is as though her lightness pulls her toward heaven, but the extra gravity around her keeps her earthbound.
