I'm not sure what you mean.
Have you found a statement from the friend that she called? It might have been useful to double-check the time, date and any other details.
I'm sure what you mean, Carana. You know perfectly well that nobody on this forum knows the answer to your question concerning Mrs Fenn's friend, i.e this question has no pertinence whatsoever. The PJ very likely made sure there was no confusion of date calling Mrs Fenn's friend (easy access to her phone nb).
Yet you recurrently insist on the double-checking of old and unfortunately late Mrs Fenn as if she was affected by some kind of Alzheimer because she heard crying on the 1st of May in the flat downstairs.
Do you suspect an hallucination ? There's no evidence the McCann children never cried, at least when they were left alone.
And about the crying stopping when the patio doors slide, there's no evidence as well that the McCann parents didn't have dinner outside.
On the 2nd, according to an alleged statement of Madeleine McCann, she and a siebling cried. A double checking with Rachael denied it.
No triple checking with Mrs Fenn was possible since she said she wasn't home. Ah but was she really out ? What if she thought she had dinner downtown when she was watching the BBC News and thought she was home when she was on the beach ?
Would you have the courage to double check Mrs McCann's who extraordinarily, in what was likely the most distressful situation she had ever lived, found a way to ridicule Mrs Fenn who kindly showed her concern ?
