Years ago, I asked to take a personal day off from work after a family cat passed away. My supervisor's response was compassionate and considerate. "I understand," he wrote. "When our dog passed away, the best thing we ever did was get another (one.) Although (getting a new pet) never replaces the old one, it started a whole new set of memories for the family."
I always feel lucky to work for or interact with anyone who understands that pets are part of the family.
