This was s National Book Award Finalist in 1999. It's not hard to understand why. Thompson writes gorgeous short stories. She has several other collections as well as a few novels.
A heart attack drops the price of the house and the couple buy it. The widower still stops by to see what improvements they are making. The wife is tolerant of this but the husband finds it irking--perhaps because it makes him doubt their ability to have a long and happy marriage. Great story. Great writer.
