I'm currently reading Olive Kitteridge (and no, it's not because of the new mini-series...what do you take me for?), and I must say I'm impressed with Strout's character development skills. Some of the people in the book only get a few pages, so to be able to convey enough in those pages to leave your readers not only understanding a character's background and motive but also wishing they could keep reading about said character is a skill indeed. 

As a person somewhat prone to annoying things like worrying, perfectionism, and overanalyzing (and also as a person who has seen If/Then), I’m fascinated by the traveling salesman problem, which has to do with determining the best way to make a series of deliveries or stops.
