An old boss of mine had a sign on her office door that said "The more I know people, the more I like my dog.". I found it humorous, but somewhat true.
After a long day at work, dealing with people and their bad attitudes, or simply rude behaviors, or impoliteness, I come home to my dog. My dog is so happy to see me. She acts like I'm a goddess and I have blessed her with my presence. She is never rude or impolite, and she would give anything to lie down next to me with a good book or movie, and it's my choice, she doesn't care which I pick, she's just happy to be near me.
Maybe that's why. No conflict. No confrontation. No thought-provoking ideas, criticisms or suggestions, just me and you loving each other's company. Simple.
