Suppose you have been with a lover for a while, but that he or she decides to break off the relationship. Because of the contrast effect, there is an initial reaction of grief. You may then observe your mind play the following trick on you: To reduce the pain of separation, you redescribe your lover to yourself so that he or she appears much less attractive. This, obviously, is a case of sour grapes, or adaptive preference formation. You then notice, however, that the endowment effect is also affected. By degrading the other, you can no longer enjoy the memory of the good times you had together. In fact, you will feel like a fool thinking back on the relationship you had with an unworthy person. To restore the good memories you have to upvalue the other, but then of course the grief hits you again.

Dr Pierson, the minister of the parish, did read the service for buriall and so I saw my poor brother laid into the grave; and so all broke up and I and my wife and Madam Turner and her family to my brother’s, and by and by fell to a barrell of oysters, cake, and cheese of Mr Honiwoods, with him in his chamber and below—being too merry for so late a sad work; but Lord, to see how the world makes nothing of the memory of a man an hour after he is dead. And endeed, I must blame myself; for though at the sight of him, dead and dying, I had real grief fo ra while, while he was in my sight, yet presently after and ever since, I have had very little grief for him.

And here do see what creatures widows are in weeping for their husbands, and then presently leaving off; but I cannot wonder at it, the cares of the world taking place of all other passions.
