Growing up, we had a dog (Digger) and a cat (Gus). Both were healthy, and for years they were best friends. My dog always wore a collar, and I guess we took for granted the sound that it made when he was walking around. Anyway, years after his death, in the garage we found his collar and my brother picked it up... it made the sound that surprised us all with its sheer familiarity -- it was just as if Digger was walking into the room. Not three seconds later, Gus the cat tore into the garage, excitedly looking for his old best friend.
I love my pets, but I've never cried nearly as hard over them as I did that day.
