A young man wandered through the desert for forty until he reached a beautiful castle at the top of a mountain. There lived the sage that he was looking for.

    With considerable patience, the sage listened attentively to the reason for the boy's visit, but told him that at that moment he did not have time to explain to him the secret of happiness.

    He suggested that the young man take a walk around his palace and come back in two hours' time.

    “However, I want to ask you a favor,” he added, handing the boy a teaspoon, in which he poured two drops of oil. “While you walk, carry this spoon and don't let the oil spill.”

    The young man began to climb up and down the palace staircases, always keeping his eyes fixed on the spoon. At the end of two hours he returned to the presence of the wise man.

    “So,” asked the sage, “did you see the Persian tapestries hanging in my dining room? Did you see the fantastic garden that the Master of Gardeners spent ten years in creating?”

    Embarrassed, the young man admitted that he had seen nothing.

    “So, go back and see the wonders of my world,” said the wise man. “You can't trust a man if you don't know his house.”

    Now more at ease, the young man took the spoon and wandered again through the palace, this time paying attention to all the works of art that hung from the ceilings and walls. He saw the gardens, the mountains all around the palace, and the delicacy of the flowers. Returning to the sage, he reported in detail what he had seen.

    “But where are the two drops of oil that I entrusted to you?” asked the Sage.

    Looking down at the spoon, the young man realized that he had spilled the oil.

     “Well, that is the only advice I have to give you,'' said the sage of sages. “The secret of happiness lies in looking at all the wonders of the world and never forgetting the two drops of oil in the spoon.”

    Ask any kid, and you'll likely hear that time spent with friends is the coolest and most important part of the school day. Educators, as well, acknowledge that making friends is one of the most valuable things children do as they learn and grow. But many parents are perplexed by their children's social lives, wondering how to help their kids cope with the challenges, heartbreaks, and the joys of making friends, losing them, and making friends again.

    “Friendships help children gradually learn to be independent, contributing members of a community and it's just as important as their academic growth” notes Diane Levin, Ph.D., author of “Remote Control Childhood.” However, it's a slow process. There are many social skills to learn, which advance with age and experience, trial and error, and experiencing the satisfaction that comes from contributing to an ongoing friendship.”

    “Friendship starts as soon as children can crawl off their parents' laps over to another child,” adds Michael Thompson, Ph.D., co-author of her life with you to her life with her friends. but who their friends are, how they interact with them, and how popular they are, is something parents have only limited control over.”

    Experts on children's behavior say that problems like jealousies, breakups, bullying and teasing account for a big part of what parents, kids and teachers talk about, and what parents worry about.

    Get insights into how children's friendships develop and how parents can help, if needed, and find ways to determine if your child is at risk for serious social problems or simply suffering from real (but common) social challenges.
