Reading and Yahoo Answers

Sometimes I forget that not everyone reads as much as I do, so I get real frustrated when I come across people that only read part of something and think they know what you mean. Or maybe they're reading what they want and not what's really there. I asked a question in Yahoo! Answers, it was:

Does anyone know about the real case that is similar to the one that the movie Changeling is based on?
I remember seeing a story about a case that was similar to the Collins case. The movie Changeling is based on the Collins case, but I remember one that was like it on a crime show. In the one I remember, the mother could not be positive that the boy they returned to her was not her son because it had been too long (maybe a couple years) so she raised him as her own. The family never knew for sure if it was the right boy or not. Does anyone know what I'm talking about?

The answer I got back was:
I asked a question about this a while back....have a look at the answers i was given http://uk.answers.yahoo.com/question/ind...

When I looked at this person's question it was:

Who is Angelina Jolie's new film 'The Changling' based on?
I've heard this film is based on a true story and was wondering if anyone could tell me about it as it sounds really interesting. Also if anyone has seen the film is it any good??

This is not the same question I asked! So I clarified:

Please re-read my question. I'm not asking what case the movie is based on, I'm asking about another that I remember hearing about that was similar. It was not the one about Christine Collins but about another mother who actually raised a son that was brought to her but may not have been her real son.

And this is the answer I got:

The Wineville Chicken Coop Murders

Which is the story that the movie the Changeling is based on! Seriously, are people stupid? Why do I feel like the only sane person here?
