You may be very happy with your life — and that’s wonderful — but that doesn’t mean everyone else wants to live their lives just like you do. Consider this when you judge how others live. Learning to judge less & appreciate differences is a good thing.
No single person is going to solve all of the world’s problems, but we can all make a difference by leading by positive example and not resorting to the kind of behavior that perpetuates negativity, increases hate, promotes intolerance & encourages violence.
People who don’t mingle with other people outside of their social, ethnic, religious, economic, political, or peer groups are like dogs that grow up without ever having been socialized with other dogs (they tend to be skittish around the unfamiliar and react to other dogs with hesitation, suspicion, and barking).
Socializing dogs is recommended for good reasons. Not least of which is that they exist more harmoniously with other dogs.
This doesn’t just apply to dogs. The world is a dog park.
