I think if he really is there he has a responsiblity to confirm he is there, and that he is interested. This would not solve all of the problems but would at least hopefully take care of some big ones.
Many people believe he has confirmed that he is there and that he is interested. Many do not believe this. Must he satisfy every person of this? If not, what standard should be applied? What exactly would it take to convince you personally? How much would be sufficient?
