My best friend

I dont know if I have a best friend, I think I have many and different friends, different kind of relationships. In this moment I have some friends more close to me, for different reasons, They live really  close to my hause or we have similar interest. But exist one friend, called, Robin, He is like a brother to Me.
I met him in the summer in Combarbala, when I was walking my dog, and he made me a questions, so many questions. after that I moved on to Combarbala and started a friendship with him. Im not sure but I think we have been friend for ten years, it is a long time. I consider robin My best friend or My brother, because he is always there, we rely on each other in any situation, we pass our lives together.
I dont know what the best memory with him is, because we have so many good memories, I cant choose any one.
