The Son was rude. Rude and unfeeling in his treatment of his mother. He should be polite no matter to whom he is speaking. With his mother, one would expect he would show a level of care and respect. Respect embodies a knowledge and humble appreciation of the person, their qualities, what they have done for you, a desire to do what is best for them and to treat them well and not hurt them, a desire to show them you love and appreciate them and would not hurt them. That is not authoritarian.
I hope you will take on board what GoodMama has written above.
It is not authoritarian to remind a son who is being rude and unkind that he is speaking to his mother. The relationship is very special and the bond of love is huge. His ability to hurt her is therefore so much greater than if her were talking to a person with whom he works. He does need reminding that it is unkind and disrespectful to give a lecture to his mother about a small matter and to make her feel a level of distress that made her lose confidence with him and to say "I now feel I can't tell him my news in case I get another lecture and feel bad." Her words demonstrate he has damaged his relationship with his mother. He needs to take responsibility for this, make amends, show that he realises that lecturing his mother is not right. To compare her unfavourably with her DGD is inappropriate and hurtful. Anyway, it is only his view.
It makes me wonder why his daughter is so perfect. I imagine with such a controlling father who has such rigid views about small things and who is given to rendering stern unsolicited and crushing lectures when he is displeased with the behaviour of someone over a small matter that is of no concern to him... well... being raised in a regime of vigilant control with strict rules regarding the right way to do things and heavy penalties for infringements, wouldn't that lead to behaviour that is immaculate? Wouldn't a child living in this condition, knowing there is only one right way of doing a thing, fearing a crushing telling off, follow his rules to the letter? No child would dare put a foot wrong living in that atmosphere of threat! Living under the constant knowledge that any step out of line will bring down such soul destroying heavy criticism, would lead to very careful and perfect behaviour.
To get so worked up about the £15 eBay jumper is not normal behaviour.
To lecture one's older mother in such a serious and unfriendly tone, putting her down, making her feel apprehensive about talking to him about another matter for fear of another put-down, for a small thing such as this, is not normal behaviour.
It suggests a need to control. A need to condemn. A need to crush another person for something which is not important, and which is not his business and which was just an item of everyday chat. To turn an everyday chat into delivering to his mother a crushing lecture about the treatment of a £15 eBay purchase, that she gave to Charity, is crazy!
Alexa Perhaps it may be worth thinking, Alexa about why your DS is getting so worked up about such a small matter. Is he always like this or is this something new? Maybe he is feeling under pressure.
Whatever the situation, I think I would try and say to your DC that you are fearful of telling them something because you felt so demeaned/put down by your DS and do not want to go through that again. I think you have the right to say you feel it inappropriate for a person to speak to another that way and are especially hurt that your son spoke to you so critically in such an unfriendly tone, which the actual incident did not deserve. But refuse to discuss the eBay thing again!
Good luck! Try to let it go and not upset you. You know you are a decent and sensible person!
