This might be a bit soppy but my dog taught me the value of life. I didn't grow up around animals so, therefore, had no real affinity with them. My boy's personality, quirks, likes and dislikes have really taught me the importance of treating all living animals with the respect and kindness they deserve.
Oh and the importance of enjoying the simple things. Nothing better than a long country walk (and a roast to come home to) on a Sunday
What are yours?
