Dogs are different. They are the best companion because they do not judge you. They are always looking at you with longing eyes, unconditional love. They always wag their tails when they greet you home. We have to learn a lot from dogs - especially in treating our companions. When your spouse comes home after a days work ( or both coming home after a days work from both), do you always greet each other with open arms and full of love as though this is the first time you meet each other? Dogs do that. We human have a lot to learn from dogs.
