We could learn a lesson from these two

This is one of my favorite pics.
It was taken in Paris in front of Galeries Lafayette. For several years running, every time we passed by this store, these two were out in front of the store with their owner.
They were oblivious to the people walking by.

My youngest son thought it was great that a dog and cat got along so well. He wondered why people sometimes have so many problems getting along especially after seeing these two. I wonder that myself.

Food for thought.
