Yeah, there's a totally inflexible cultural expectation of parents to be there for their kids no matter what, with no regard for bedrock emotional and psychological limitations or even common sense. Incidentally, I think this is why so many people are shocked and appalled when they become adults in the big bad world and discover that it isn't devoted to them. It's a tough gig for the best of us but if you've been brought up with an illusion of god-like figures who can unfailingly be summoned at all times to protect you from everything then I think adulthood is a wake-up call that probably never ends.
