1.) The world is life itself where all humans are actors and actresses who enter, portray their own lives, and then exit when they have finished with their roles.
2.) Men and women play out their roles in life, beginning with their birth (entrance) and death (exit).
3.) Humans are not the same all their lives. Their life is a series of changes as they grow as a baby, but soon exit infancy to enter childhood and adolescence. But 87 they eventually exit that stage to enter adulthood. For each stage they play different roles. Eventually they take the final exit (death).
4.) From being an infant to child, a kid to what I am now, I play the role of a loving daughter and a sister to my younger brother, and a student now, who's studying hard to achieve my goals and my dreams.
