Robert has been an imaginary twin brother to Lillian for over eighteen years.After the sudden and deliberate death of their older sister, Robert is forced to confront the inevitability of his own death as an imagined being.Interspersed between Robert's grappling with the logistics of what he is, are the voices of his family members: Lillian, who needed an imaginary friend late in life; Lacey and Samantha, the older twin sisters who grow apart on purpose; and Jillian, the result of a teenage pregnancy, who feels she's treated more like an imaginary being than Rob is.The Moment You Remember, You Forget challenges the perception of what is real by exploring the boundaries of love, dependency, and grief.
