SCENE II: Belmont. A room in PORTIA'S house.
Enter PORTIA and NERISSA
PORTIA
By my troth, Nerissa, my little body is aweary of
this great world.
NERISSA
You would be, sweet madam, if your miseries were in
the same abundance as your good fortunes are: and
yet, for aught I see, they are as sick that surfeit
with too much as they that starve with nothing. It
is no mean happiness therefore, to be seated in the
mean: superfluity comes sooner by white hairs, but
competency lives longer.
What does the line 'Enter Portia and Nerissa' indicate?
