What was the deal and the point of the scene with "Joe" the lodger?
Besides it being what it is, what message do you think was meant to be conveyed there? Also...
Couldn't his parents have exerted themselves more than cry and passively listen when he was saying all that stuff about Alex and how he is an irredeemable monster and all that? Could they not also have offered him REAL shelter elsewhere and have claimed that, for instance, he could stay there for a while and you can live here - especially in his state and no job after his release, he wouldn't be able to afford a part time property anywhere to rent or stay at the time?
And also, when Joe claims that he has read about all the "many horrible things he's done", for all he and the mass media knew, he was only arrested for and charged with accidental killing (and it was somewhat proven it was an "accident") of that one woman and not for many other crimes that we knew he was responsible for, but how did he know about "so many other bad deeds he has done"?
And what if the father and the mother really did throw a fit and Joe and said to him "Stop it, don't be rude or we will throw you out?" and just express their disagreement, yeah, I know it would've been a different movie but still...
Alex may have been unhappy for a while but could his parents have offered him shelter elsewhere?
But besides all of this, what was the point of this scene and what message was it trying to convey?
That when you commit serious crimes and later get released, one way or another your life will change for the worse even when you're out and you could face inconveniences such as revolt from certain members of the public and even discomfort within your own family?
P.S. And let's say Alex didn't throw a huge fit and actually allowed Joe the lodger to stay, had forgiven him for saying all that stuff and didn't hold a huge grudge on his parents for passively being on that guy's side and actually asked "So where can I live now?", would his parents have afforded to rent him a room somewhere else at least for a little while? And couldn't Joe himself, his parents etc have been at least a little more DIPLOMATIC in the process and negotiate the terms and conditions no matter how much "sentimental value" (and it did apparently!) his home and place had to him, never mind also Alex fearing for his life later as it turns out from that homeless men and his pals, his former Droogs turned cops in an unfair twist of events and Mr Alexander later himself, if such thoughts even DID cross his mind.
