I was listening to The Stranglers‘ superb rendition of Walk On By (a song originally written for Dionne Warwick) and suddenly it seemed to me it was about Misuzu in the classic “sadder than Grave of the Fireflies” series, Air.

And I start to cry
Each time we meet
Walk on by, walk on by….

It just seems to sum up her situation perfectly… whenever she gets to close to people she breaks down and cries, and not knowing what to do, people just walk on by….
