24 | "Happy families are all alike; every unhappy family is unhappy in \ | |
25 | its own way. \ | |
26 | \ | |
27 | Everything was in confusion in the Oblonskys' house. The wife \ | |
28 | had discovered that the husband was carrying on an intrigue with \ | |
29 | a French girl, who had been a governess in their family, and she \ | |
30 | had announced to her husband that she could not go on living in \ | |
31 | the same house with him. This position of affairs had now lasted \ | |
32 | three days, and not only the husband and wife themselves, but all \ | |
33 | the members of their family and household, were painfully \ | |
34 | conscious of it. Every person in the house felt that there was \ | |
35 | so sense in their living together, and that the stray people \ | |
36 | brought together by chance in any inn had more in common with one \ | |
37 | another than they, the members of the family and household of the \ | |
38 | Oblonskys. The wife did not leave her own room, the husband had \ | |
39 | not been at home for three days. The children ran wild all over \ | |
40 | the house; the English governess quarreled with the housekeeper, \ | |
41 | and wrote to a friend asking her to look out for a new situation \ | |
42 | for her; the man-cook had walked off the day before just at \ | |
43 | dinner time; the kitchen-maid, and the coachman had given \ | |
44 | warning." | |
