Just this side of heaven is a place called Rainbow Bridge.
When an animal dies that has been especially close to someone here, that pet goes to Rainbow Bridge.
When I got home from work this evening, I found my best friend, perhaps my only true friend, lying dead at my front door. Since he was not yet cold or stiff, I can only surmise that he knew I was on the way home (I was delayed by several events) and used his last ounce of strength to let me know he loved me and was glad I was home.
