You'll go crazy waiting for people to change for the better. You can only change the way you act and react. Somebody got it right a long time ago with the "Golden Rule".
JJEH, so how do you like wrestling with pigs?
Bottom line: Don't let them get you down. It's just not worth it and you likely are not going to change them. If you find it bothersome or frustrating, go to the pistol range or fishing instead. Otherwise, try to reason with those that cannot be reasoned with and enjoy the challenge.
Where I grew up, if you hit a patch of ice and ended up in the ditch, at least 5 or 6 people would pull over and help. Around here people just keeping driving by. They could care less. But if you didn't stop to help them, then you're a selfish idiot.
Selfishness and greed is destroying this country.
