Every morning since he had returned home after Robin’s death, Crystal had noticed a small green and yellow bird waiting at his window, trying to get his attention by tapping at the glass with its prominent beak or by flying up and hovering ostentatiously. “It keeps pecking at the window and it wouldn’t fly away,” Crystal said. “It wasn’t scared. And I’d hit the window back and it would do it back to me, and then it would fly up and land on this little leaf. Over and over again. It’s weird.”
