I read a novel in verse a few years ago called Sharp Teeth, by Toby Barlow. Near the beginning he writes:
Everyone has a dog story to tell...
Each dog marks a section of our lives, and
in the end, we feed them to the dark,
burying them there while we carry on.
Today is my dog's birthday-- she's seven. Seven in people years, seven times seven in dog years. According to that common calculation, she is now older than I am.
Happy Birthday, Isabel.
