What does Linda think is the trouble with Willy's life? Why is she angry at her sons? Why does she put the rubber hose back after she had taken it? What does this tell about her?

1) Linda thinks that all of Willy's problems/troubles will be solved if he thinks he's accomplished something by making his sons successful. His feeling like a failure, in her mind, is the trouble with Willy's life.

2) She's angry because they don't care about their father and make him feel unwated.

3) Linda puts the hose back because she wants Willy to take the hose off himself. To confront him with the hose would be to insult him and his sense of pride. This act shows how compassionate she is; she waches and knows what will best help her husband.
