Actor Adjoa Andoh's son sensed from a very young age that although he inhabits the body of a girl, he was born a boy. "In the imperfect language we have to describe people," she says, "we call him transgender." Adjoa talks movingly about raising a transgender child, and about what really defines who we are or who we might become. "In too many places today," she says, "and in too many ways, we suffocate our true potential selves at birth." Four Thought is a series of thought-provoking talks in which speakers air their thinking on the trends, ideas, interests and passions that affect culture and society in front of a live audience.
