lol!! its funny, but its sad.
His mother obviously has a HUGE problem.
If that problem proceeds the mother could turn out like that Mother in "Requiem For a Dream"

ops: hah, nah, just a thought
This is what I would do if I were him:
1: Really talk to her about her problem and consult her to a therapist, possibly paying for her if she really refuses it
2: Sell that shit
3: Disconnect the PC (or password protect it if I use it alot)
4: Ask two people to help me organize the home
I have a problem similar to that where I just leave things allover place (hah, probably due to disorganization and pure laziness) but I end up cleaning it two weeks later which is just annoying, so I feel for the kid.
