"One of the themes of this play is the conflict
between conformity and freedom. Cite speeches or
stage directions that illustrate this theme. Answers
will vary. Stage directions that have the trains going
mechanically in the same direction (top of page 54, for
example) reinforce the conformity side, since when one
of the men forming the train jumps off, it disappears.
At the bottom of page 54, Flagman and Man disagree
on whether all women look alike or not, with Flagman
stressing conformity. Both the young man and the old
woman find their efforts to make a deep connection
with another person thwarted by conventional attitudes
about age. However, the woman seems to have achieved
some inner freedom, saying, “Now I’m the woman I
always wanted to be.” "
