"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."
