What a very unpleasant comment. His wife is staying in hospital for a prolonged period, and is unlikely to return to duties until after Easter, which is hardly indicative of a minor problem. Nothing has, however, been ‘admitted’..
He has postponed some engagements - in similar circumstances a paid employee (which he is not) might be given compassionate leave. We don’t know which engagements have been postponed - they may have been such as to take him away from home; remember that he has three young children who need his reassurance and presence whilst their mother is in hospital. Some compassion on your part wouldn’t go amiss.
