Oranges are not the only fruit

From the opening of the chapter Levitacus, I believe the mother is being very hypocritical in various aspects. First she judges everyone and anything that happens or crosses her path. For example she calls the neighbors heathens and fornicators. I truly do not believe she knows whether the neighbors are married or not, so she mainly just assumes that they are fornicators. And just because they do not attend her church and believe the same beliefs that she does, does not mean they are heathens. And when the "Next doors" are supposedly having sex, it drives the mother off the wall, to the extent where she begins to retaliate which I don't believe is very "Godly" like either. She starts making noise even louder by telling everyone to sing the hymns as she plays the piano. I don't believe what she did would result in any resolution of the situation, yet the mother then seems satisfied. As though she has fulfilled her purpose.
