we do it obsessively

I need a new bike. I refresh my craigslist window somewhere around 500x per day. Recently, after my bent chain guard was crunched by the pedal, my bike's chain fell off. I am capable of putting a chain back on a bike, but not of resetting the gears on this little 3 speed Triumph. So instead of trying to fix it, I just want a new old bike. In the meanwhile, I'm stuck in one gear, no doubt the hardest gear, and arrive at work a red sweating panting mess each cool morning.
