A lot of people are similarly confused by my biking when I tell them I don't have a car, and that I decided to use the money for down payment on a house instead. Typically they think I'm talking about living at the very edge of my income or something. They offer to help me figure out how to save better and get all pissy when I tell them I have enough cash saved up now to buy a new car, I just am waiting for one I like to come along.
