Hachiko: A story of true friendship

It is often said that a man's true bestfriend is a dog. Am not a dog lover but I don't hate them either. I  watched the movie Hachiko: A dog's story. The story moved me to tears.  It was about loyalty and love.

The story revolves around a dog named Hachiko who unconditionally loved his master.  It was a routine for the dog to walk his buddy to the train station when he goes to work and he wait for his arrival from work at the train station every afternoon.  The master died suddenly of heart attack.  The dog keeps going back to the train station to wait for his buddy to come home.  Hachiko waited for his buddy until his death.  He waited for nine years.
