In (DELETE "IN.") the short story(COMMA) "Trifles" by Susan Glaspell, describes a wife who slowly loses her identity and conforms her husbandís wishes, which leads her killing to kill her husband. When the Attorney (NO CAPS) and sheriff come to investigate the murder (COMMA) they view the wife as trifling. Because the house is not in order (COMMA) they immediately begin to judge her ó not her husband. The Theme (NO CAPS) of the story is based on the power of observation between the men,(NO COMMA, "AND.") women and the role they play in society. Minnie Wright acted out of rage and lost her sanity because of isolation, gender difference(S) and her unhappy marriage. (I ASSUME MINNIE IS THE WIFE, BUT I AM NOT SURE. NAME HER AT THE BEGINNING OF THE PARAGRAPH.)
Caps are for contrast only.
You need to review your use of commas.
In the future, if nobody is available to proofread your work, you can do this yourself. After writing your material, put it aside for a day ó at least several hours. (This breaks mental sets you might have that keep you from noticing problems.) Then read it aloud as if you were reading someone else's work. (Reading aloud slows down your reading, so you are less likely to skip over problems.)
If your reading goes smoothly, that is fine. However, wherever you "stumble" in your reading, other persons are likely to have a problem in reading your material. Those "stumbles" indicate areas that need revising.
Another option, if it is available on your computer, is to have the computer read it to you.
Also, make use of "Spelling and Grammar" under "Tools" in word processing program.
Once you have made your revisions, repeat the process above. Good papers often require many drafts
