How much responsibility do you think a son needs to take for his parents finances ? Let's say he's 23. His dad made some HORRIBLE decisions and got sued by the government for millions. So now obviously his wife got fed up and left him (she had put up with his stupidity for years, she's not a gold digger or anything) and she got a job and moved out, etc. But dad has crappy credit obviously and is making his son help like by putting his name down for a house. Or paying the hydro bill for instance. He already pays rent for lodge groceries and Internet. Is this acceptable ?
