You could learn alot from a sheik.
The word trust and arab don’t belong in the same sentence. LOL!
“his entire understanding is wrong...the trust in him is not very high...he will not have an easy ride...”
Is that the best they can do, ask him hard questions and let him ride them but not make it an easy ride? If his entire understanding is wrong, and the trust is not very high, you humor him and then do whatever you originally planned to do; i.e., something based on a true understanding, dealing with people you can trust more than him.
