<human>:  I have a question about a famous photograph by Dorothea Lange. Why is the woman in the photograph crying?
<bot>: The woman in the photograph is a migrant worker, and she is crying because she is about to be deported back to Mexico. The photograph was taken in 1936, and it was taken during the Great Depression. The woman in the photograph was a migrant worker who had come to the United States to work in the fields. She was a Mexican migrant worker, and she was about to be deported back to Mexico.
