Nostalgia: I think I will interview a few students and professors and compare/contrast their feelings about what makes them feel nostalgia. There will be interesting generational differences!
Obsession: I think I will make this one just about students. What do they feel they are obsessed about, and why? Do their friends understand their obsessions, or do they think they are weird? I am curious to find someone whose obsession is unusual. 🙂
