playing nice with others

I've noticed that I don't play very nicely with my marketing management group at school. This saddens me, because I generally feel like a fairly likeable person, but I think there's a 100% chance that the group members have all built dart boards in effigy of me ever since I sent hate mail telling them to pull their shit together. It's gotten awkward. 

Each week, we all write sections of a marketing plan that have to be edited together to make one formal APA-formatted paper, which we submit every week. Feel free to let the word formal echo in your head a few times. I really try to put a lock on my holier-than- thou editor's attitude because my group consists of very nice middle-aged accountants who use words like "supper." I'm sure they have many talents. Unfortunately, reading and writing don't seem to be two of them.

Things that make it difficult for me to not send them expulsion letters:

-One member edited the paper this week and left this sentence in. "Traffic counts – Determine the customer use of the store, If traffic counts are below estimations, is it consist during open hours or is it cyclical from weekday to weekend." When I pointed out that it wasn't a complete sentence, his response was "Grammer check did not note it." Mkay.

-Our teacher is an APA nazi, and when I said that our headings in the paper needed to be adjusted to match the correct style, he said he disagreed because he turned in a paper to another teacher once and that particular teacher didn't comment on his formatting. 

-Another member didn't write her section of the paper last week because she "just didn't know what to say."

-The same woman also volunteered to edit and turn in last week's paper. Yesterday we realized she had not even copied/pasted all three sections together and no edits had been made after we spent 2 hours in the library discussing changes. Oh, and the text was centered.

-When I devastated my group with the information that, no, Wikipedia was not a legitimate resource, they agreed that we should "just turn in the paper and see what the teacher throws back at us."

I'm considering suggesting that the professor administer a test on sentence construction as a weed-out.
