Shortly after moving to a small town north of San Francisco, I found a note in the mailbox from a neighbor. "We’re so happy to have more children in the neighborhood, " Rhonda Anderson wrote. "Please come for tea. "
   A few days later my two-year-old daughter, Julia, and I made our way down a brick-lined path into a brand new friendship. In the nine years since, Rhonda and I have been best friends. We have taken the kids to the zoo and the circus together. We have enjoyed many movies together. And we have even taken several trips abroad together.
   But it’ s the times we’ ve leaned on each other that really come to mind. When storms knocked out the electric power, our families stayed together in candlelight. Once, I briefly left my ten-year-old daughter home alone and returned to find her held closely in Rhonda’s arms. "I felt sick, so I called Rhonda, " Julia explained.
   Close fiends are like that. A friend drops her plans when you’re in trouble, shares joy in your accomplishments, and feels sad when you’re in pain. A friend encourages your dreams and offers advice—but when you don’t follow it, she still respects and loves you.
