Shari Willison worked as a geologist in your civil engineering firm for 20 years before succumbing to leukemia last week. With only a few dozen employees, the company has always been a tight-knit group, and you feel like you’ve lost a good friend in addition to a valued employee.

Your task: Write a letter of condolence to Willison’s husband, Arthur, and the couple’s teenaged children, Jordan and Amy.

You have known all three socially through a variety of company holiday parties and events over the years.
