<human>: Can you give me a shortened version of the text?

I need some help in understanding this concept.

so my speech teacher says that environment should dictate the way that we talk. She said that if you were eating at your house with your parents then the conversation would be different from a conversation at a public restruant (which I disagree with). She said that your family would be more quiet, out of consideration for other people, and talk less about personal things (because people around you don't want to hear it). Then she said that the situation would be very different if you were with a group of your friends (agreeable). She said everyone is more inclined to speak loudly and not care about who overhears what disgusting things you say. She then went on to say that was a HUGE problem in communication, because people should respect the environment and make choices according to their environment. 

When I asked her why her overhearing some teenager's uninteresting story was such a HUGE problem to her she said that when people don't respect the environment people get their feelings hurt and retalliate by killing or hurting people (that's seriously what she said). When asked what evidence she had to back it up with she said there were plenty of studies to uphold her argument (although she couldn't give me any of the names). I told her that at a bar the environment is already shady to begin with because of the kind of people associated with the bars, plus the alcohol and its effects on people. She said that that wasn't true not all bars are like that and that Chilli's was a perfectly nice place if people would act accordingly to the environment. 

I couldn't continue because she was so mad at me by that point she made me leave the room. I want to have some research or anything so that I can come back tomorrow and slap her across the face with my dick made of strong arguments to the point that she realizes that she is just being a whiny baby about the whole thing.

please help by stating your opinion, and if you know any research on the subject let me know.
<bot>: Whiny teacher thinks that you should act according to where you are not according to who you are with because she doesn't want to overhear loud youg'ns talking about gross things while she eats.
