I believe everyone, is born with a `sixth sense`, It lessens as we age.
Children are more likely to tell the truth, they dont know how to tell lies, I wish I`d listened to my daughter more as a child, I could have learnt a lot from her.
We all have `spirit guides`, or angels, & to a degree, its that that guides us through life...its knowing whats the right thing/wrong thing to do.
This story, I beleive....something told (david) the family to keep looking, how that instinct can be explained..
I cant, at least the family is now pulling together, I wish them all good luck, health & happiness xx
