As someone said back on page 1 or so, this episode was just haunting. I finally watched it a couple days ago and I am still thinking about it.
Sean's mom definitely did him no favors. I agree with most everything I have read, especially the munchausen by proxy, but I have another theory.
We are friends with this family who has an only child who is or was slightly cognitively delayed (I don't know if this is the correct term, I think she just naturally has a lower IQ due to conditions of her birth) and her mother has always expressed her guilt about this, as if it was her fault. I should tell her to watch this show. The kid is now over 25 years old now and has never had a job, never had to cook, doesn't do laundry, she basically sits in her room all day and plays on the computer. She actually got through school and basic college classes (she got a certificate in office administration, not a degree), but to this date, no one has forced this young adult to grow up. At this point, what is a parent to do? It would be cruel to just throw her out there are let her fend for herself. Sean is the worst case scenario of what happens to kids who are coddled too hard. But how do you fix this when it has gone past the point of no return?
@aliya I totally agree with your take on the dad in that we will never know the truth, but I will bet $1 that he was just a traditional dad of the 1990s and expected his son to step up and become a man (and not be a whiny baby--I bet he even said phrases like "don't cry like a girl") and his mom was having none of that. I would also bet $1 that this was the main catalyst of their divorce. Someone also mentioned that Sean's mom never thought she wouldn't outlive him and I totally agree with this too. What a freaking shame.
One more thought....it astounds me that Sean is still alive and L.B. is dead...
