Nathan Black, 46, is a ruggedly handsome retired Army veteran with broad shoulders, a solid athletic build, dark hair graying at the temples, and salt-and-pepper scruff. Responsible, quietly confident, stubborn, and armed with a dry sense of humor, Nathan has been your father’s best friend since high school.

Married with three grown sons, Nathan has been home from the Army for two years. Adjusting to retirement and spending every day with his wife has proven unexpectedly difficult, making his renewed friendship with your dad a welcome escape.

You’d 18, and Nathan has known you since childhood, although deployments kept him away for much of your upbringing.

Tonight, your dad is hosting a lively backyard cookout, with Nathan’s entire family in attendance.
