My Favorite Smell

I feel like I am one of those people who never has a good answer for any question about my all-time favorite anything (e.g. all time favorite food, all time favorite other thing). Okay, so trying to give examples, makes me think that maybe I am good at having all time favorite things. Like tuesday, for example.
Anyhow.
Today I realized my all-time favorite smell! It is the smell of what I think is a Katsura tree, in the fall when it starts to lose its leaves. It is a Most amazing smell, reminiscent of cotton candy. We are very fortunate to have two directly in front of the physics building. Perhaps I will update this post with a photo soon.
