Have you ever had it where,
There is some guy you always see around your neighborhood and he looks kind of crazy? You don't think he is actually homeless but he looks borderline. Grubby clothes. He's got the grey hair ponytail and unkempt facial hair. He has that really thin wiry frame that some alcoholics end up with.
But you keep seeing him around town and he is never doing anything crazy. He is always just walking here and there calmly. And one day you suddenly think, 'What an asshole I am. Why am I so judgmental. So he's probably not rich and he has different ideas about hair than me - but why am I jumping to conclusions? He actually doesn't look a lot different than my brother who is as good-natured, gentle, intelligent a guy as you would want to meet.'
You give yourself that mental reproach and from that point on you change your assumption. You see him walking along the street and you think, 'There's my neighborhood buddy. Good guy.'
And that lasts for years and years. It becomes woven into the fabric of your thinking.
Then suddenly one day - for the very first time - you see him speak, you see him in action. Out of the blue he suddenly starts yelling and shaking his fist at traffic from the sidewalk: "Move it asshole. We need the space. Stop making the RAIN!"
I had that experience today.
