In any essay, short story or novel, there will at least be a thesis statement which will indicate the writer's own perspective and basically present his or her argument in a nutshell. The thesis statement is intended to persuade the reader towards a particular point of view or to reveal the focus of the story. Having read the thesis statement, the reader will have a better idea of what to expect in the story. It usually appears close to the beginning, even in the first paragraph and gives the reader a hint how the writer intends to deal with the theme.
In Thank You, M'am by Langston Hughes, Mrs. Luella Bates Washington Jones represents an intuitive, compassionate and honest woman who knows the difference between a boy who is nothing more than a thug and one who is in need of some parenting. The story centers on the effects of economic circumstances on young people whose parents (unwittingly or otherwise) neglect their children while out making a living. Mrs. Jones is and has also been affected by her own situation; a woman out working late shifts, trying to make an honest living, and can relate to Roger, recognizing that showing him some kindness and respect will serve a far greater purpose than punishing him.
The thesis statement will:
1. hint at what the reader can expect
2. guide the reader towards interpreting the writer's perspective
3. contribute towards understanding the theme
4. be found close to the beginning
5. give direction
Therefore, in my opinion, a good thesis statement would be " You ought to be my son. I would teach you right from wrong. Least I can do right now is to wash your face."
