Why is important to be honest with each other?

Sometimes I recall myself as a child. One day, this dude was 8 years old, he was heavily trying to persuade his parents that he saw Santa Claus coming through the roof. He was so excited about it that he called his dad and said: "Hey dad! Come here and check. This is where Santa went through to bring me my present." Luckily, my father was kind to me since I was just 8 years old: "Tell me, son are you sure the Santa can fit and pass through this tube?" I was shocked for a moment, but he looked back at me for a moment and smiled and said: "No need to present the things as you wish them to be. Present them as they are because soon you will find yourself trying to explain what cannot be explained." I stopped for a moment in silence, really worried that he found out I was telling lies. I felt horrible and angry and I started crying. After my burst, by the miracle of nature I had my head calm, my mood at position, and my lesson learned. I was so glad I had such a realization. I keep that with me ever since. Now, why I am telling that? I am always happy when I meet people that remind me of my 8-year-old self. Some of them are so cool and they all claim that they have big money and are heavily involved in a lot of projects. They make the necessary noise so you can be aware. Most of the time they come with promises, or principals that does not last in time. Let's ensure self-respect. This may sound like common sense, but it really is a reality check. Since we may meet someday, let's atleast ensure honesty. Let's see what happens.
