Read a thing a while back about how bus rides used to be where people just watched the city go by and now everyone stares at a screen the whole time. That old guy was basically giving you free advice. My uncle rode the same bus in Chicago for 30 years and he said you notice stuff you'd never see driving, like which houses put up lights first or where the same stray dog hangs out. Staring out a window sounds boring but it's kinda the only time your brain gets to just wander anymore.
