"Happy families are all alike; every unhappy family is unhappy in   \
its own way.							    \
								    \
Everything was in confusion in the Oblonskys' house.  The wife	    \
had discovered that the husband was carrying on an intrigue with    \
a French girl, who had been a governess in their family, and she    \
had announced to her husband that she could not go on living in	    \
the same house with him.  This position of affairs had now lasted   \
three days, and not only the husband and wife themselves, but all   \
the members of their family and household, were painfully	    \
conscious of it.  Every person in the house felt that there was	    \
so sense in their living together, and that the stray people	    \
brought together by chance in any inn had more in common with one   \
another than they, the members of the family and household of the   \
Oblonskys.  The wife did not leave her own room, the husband had    \
not been at home for three days.  The children ran wild all over    \
the house; the English governess quarreled with the housekeeper,    \
and wrote to a friend asking her to look out for a new situation    \
for her; the man-cook had walked off the day before just at	    \
dinner time; the kitchen-maid, and the coachman had given	    \
warning."
