During my teenage life, I had many friends. Some of them were good while some were bad. I learned from them that it was hard to find a best friend. Sometimes, I thought I found someone who could be my best pal, yet she was actually not a good one. Ideally, my best friend is someone who walks into my life without any expectation or return from me. That means she will always helps me when I have problems and never leaves me behind. Actually, she should be nice, sincere, neat and helpful; she may have the same interest as me and is willing to share things with me. When I have to study hard, she will also stand beside me, help tutor me or be my good advisor because I will do the same to her
