    As a boy I was always small for my age. I was also five years younger than one of my brothers and seven years younger than the other. As a result, I often felt left out when their friends came over to play. I was either too small or too young for whatever they were doing and they didn't want their younger brother listening to their conversations either. More often than not I found myself outside playing alone and feeling forgotten.

I remember one spring afternoon feeling especially lonely as I sat in the yard behind our house. We lived miles from town and I hardly saw my own friends outside of school. I heard my brothers laughing from inside the house and felt a single tear coming down my cheek. At that moment I saw a large brown dog walking over to me. He looked happy and his tail was wagging as well. Even though (尽管) he didn't know me he greeted me like a long lost friend, licking (舔) my chin and sitting beside me on the spring grass. It must have been at least an hour that I patted and talked to this four-legged angel (天使). He let me pour out all my troubles and shared my deepest thoughts before he kissed my cheek goodbye and ambled off either to Heaven or his home. I went back inside feeling happy, knowing that no matter what life may hold I was loved. Now over 40 years later I still remember that angel with a smile.

I believe that God sent him at that moment of sadness to remind me just how much he loved me. There is nothing more important than knowing we are loved. When we are loved, we will learn to love others. Learning to love helps us to understand ourselves and other people better.
