Nostalgia

The word "saudade" that is shown on a Post-It note in the daughter's room is a Portuguese word without a literal English translation. It generally means a melancholy longing for something, and differs from "nostalgia" in that one can feel "saudade" for something that might not have even happened. Nostalgia is, by contrast, a sentimental yearning for the remembered or perceived happiness of a former place or time.

With the huge fire that burnt down Helen's house, the surrounding trees seems to be unharmed.
