A good listen for me.  I don't know how anyone could put up with that woman and her sister, which makes me wonder why he married her in the first place (he does say that she used to be nicer to him when they were first married).

In response to Roger's question about him not changing, I think she meant that she didn't want him to kill his new wife and/or sister-in-law with his razor as he had started thinking about doing.
