What does Janie do during the evenings?

For Janie, evenings brought loneliness..... and thoughts about the future.

From the text:

Most of the day she was at the store, but at night she was there in the big house and sometimes it creaked and cried all night under the weight of lonesomeness. Then she’d lie awake in bed asking lonesomeness some questions. She asked if she wanted to leave and go back where she had come from and try to find her mother. Maybe tend her grandmother’s grave. Sort of look over the old stamping ground generally.
