David has a tendency to pretend to not be very smart.
Yet, he can manipulate a conversation so that you believe you gave him permission to have the car for a couple of hours. The conversation could have started with something innocuous, such as, can I take the dog for a walk.
I keep telling him, that anyone who can manipulate conversations, and some people, are not stupid.
He doesn’t do anything with out calculating a benefit for himself. Sure some things he does appear to be spontaneous, but rest assured, he is thinking hard about the best way to get the situation to turn out to his advantage.
If we could just harness his ability to argue, manipulate and calculate benefits – he could go so far.
