I have been a member of webslueths for a long time. Seems like I am here a lot and then life gets in the way. So.... I don't post often. All that to say, as a family we have always traveled often to similar places as Praia da Luz. I have followed this case from the beginning. The mother in me wants to believe that the parents were not involved. I asked my husband the other night "do you recall, in all our travels when the kids were young did we ever go out and leave them alone sleeping in the apartment." His response was "We would have never done that, you would be a nervous wreck". This is a practice of some parents that I just don't get. Is this common in some cultures?
In response to your first point- I am in the medical profession. Because of the things I have seen I am very easily able to maintain control of myself in the most dire circumstances. Now, I say that also adding that I am an extremely emotional person. When there is a crisis though, I am a rock. Behind closed doors I can fall apart. Because of the McCanns background this may be what you are witnessing. I know you could argue "but the is their child", and I get that. I just feel like I could possibly behave in the same way.
As far as Kate not crying in public, I don't know. I again could see myself losing control in private, while being able to maintain composure in public.
I do agree that in public their behavior as a couple seems a bit off. Definitely G is In Charge!
I do feel that the McCanns believe that the police in Praia da Luz were incompetent, and that they themselves were superior human beings. Ummm you are in a forge in country and need all the help you can get! I wonder if that is typical of them in everyday life?
Just a few thoughts. Enjoy reading your posts.
