I know loss is part of life. I know that coming to terms with a loss can make us stronger, whether it is the loss of a family member or friend; the end of a marriage, a job or a love affair; the acceptance that physical restraints may change the way we imagined our life would be. I know we need time to grieve, to work through the stages of grief. I know all that. But some days it all seems to be so darn hard. Our dog died today. He'd been part of the family for 15 years. The house is going to seem very empty tonight.
