Query: Required Reading for Animal Lovers

I have been in the veterinary industry for over 15 years. Sadly, we often send condolence cards to owners when their pets pass away. Many years ago I started seeing a particular quote by Irving Townsend on these cards. It read, "We who choose to surround ourselves with lives even more temporary than our own live within a fragile circle, easily and often breached. Unable to accept its awful gaps, we still would live no other way. We cherish memory as the only certain immortality, never fully understanding the necesssary plan." It took over 15 years to stumble across the book that contains this quote, but it was worth the wait. I recommend it from the heart. A truly memorable experience.
