People don't understand probability

That's what they bank on

People are generally terrible at probability (most think 50/50 are good odds) but also tend to over estimate their own skill or luck. When WE speed we are in control, but another driver is reckless for it. When a friend does something rude no one should be offended, they're just funny like that; when a stranger does it it's obnoxious. And of course, talk about your hobby for ten minutes to a stranger- sure. You're interesting, and if they don't agree they're lame, but when some Melvin comes and talks your ear off about some thing you do t care about, they're a real bore, and it's understanderable you'd leave. People tend to have poor self awareness. It helps them maintain their self image.
