Rabbi Mica’el Shushan, הרב מיכאל שושן – has a series on shalom bayit / peace at home. [In program 52] He quotes the pasuk – “The end of his act – is in his thought in the beginning” – The verse – means that what Hashem intended from the beginning happened at the end. He gave another interpretation – the end of your act you should consider from the beginning.
He gave an example: Let’s say a man comes home and takes off his shoes. He sits down to eat. His wife comes in “What are you doing?! You know how much I hate when you don’t put away your shoes?! You can’t make a small act to put them away?!” She thinks he’s going to change with her tirade. Really he is not. What will happen?
Excuse the comparison – but a scientist did an experiment. Every time he would feed a dog – he would ring a bell before. After some time – when he would just ring the bell – the dog would start salivating. It became a physical reaction.
When one spouse or parent starts nagging. The person on the receiving end will start associating the nagging voice with negativity and thus have a physical reaction to ignore the the nagger. The voice of that person will trigger ignoring – even when they speak positively.
The talking person should consider what message the sound of their voice provokes. They should consider what works with the other person and do what works.
