How does Edward Albee use imagery in Three Tall Women?

The imagery is a little odd here. At the beginning of Three Tall Women, three ladies generically named A, B, and C are sitting around a wealthy, extravagantly decorated bedroom.

A is an elderly woman who insists that she is ninety-one years old. A young, bright woman, C is the lawyer for A's estate. She disagrees, and claims that A is actually ninety-two. B, who seems to be A's caretaker, is fifty-two years old and attempts to mediate the dispute. These are the three tall women of the play's title.
