What a truly horrible young man you have raised.
Rude ignorant, selfish, entitled, you name it, an absolute disgrace.
I would be beyond mortified to have raised such a deeply unpleasant pup.
He will undoubtedly be a piece of shit as a husband, as you have done a tremendous job of raising him to think he can treat those he lives with, with contempt.
That you honestly think that being even kinder will bring this ugly young adult closer to you, is so beyond deluded and sad.
When you see his relationships failing and him being a shit husband and father, you will see how you allowed him to behave in your home, come to full circle in his own life.
I have 2 sons around that age and the door would hit the back of them as they left, if they attempted behaviour like that.
I can only imagine what your life must be like if you think it is reasonable for anyone, much less your child, treat you with such pure contempt.
You have failed him utterly by allowing this.
That he lives for free and treats you with derision is shameful.
The lift should be a wake up call to just how ugly a little brat you have raised.
