Yes Puppy this is the crux of the question isn't it.
I would say we do treat them lovingly in the broader sense and respectfully but to me that is a far cry from a best friend or I would go as far to say even a friend. Maybe my idea of friendship is different to others. I have a wide circle of acquaintence's but a small band of what I term true friends and an even smaller band of best friends. Those are the people who are privy to my most intimate hopes and dreams and thoughts and who I trust to guard them as I would and do theirs.
