From my P.O.V.(point of view)...

Each of us have a different tolerence limit ...For Edna, it is difficult for for her to separate her real persona from the real world. I bet Edna's persona outside is less brutal. If Edna and Leonce can keep reminding themselves of the different tolerance limits that OTHER people have then their marriage wont be put in jeopardy. They would feel that the world will be a nicer place to be in. It would be easier to carry on their relationship as husband and wife. Then their greetings would then be acknowledged in the best possible response. It keeps the camaraderie alive. Opinions from both of them could be taken with lots of tolerance. Hot discussions flow among cool heads gracefully. Argument done with healthy airs. Right for an opinion be respected and guarded although one may chose not to agree with opinions put forth. I don't think Edna and Leonce really find it's difficult for them to separate their internal persona from the real world." In time of arguments/discussions people just want to keep up with the flow. It is just a matter of having differences in opinions. Keeping cool heads can save the day. Then Edna and Leonce would be just fine... but it does not happen the way I imagine. What a waste.... Actually, I just want to add my 2 sens worth here while finding the points to start my position paper.
