My husband underwent angioplasty a few years ago, a procedure where stents are used to widen blocked arteries, he was wiped out for quite a while after. Thomas Markle had the same operation just prior to the wedding which of course would have precluded him to travelling by air. In any case, recovery is far from immediate. To be berated in the immediate aftermath of that, still in a hospital bed, from a never met prospective son in law prioritising a vent of self indulgent anger at that moment in time was certainly an eye opener. To be admonished and probably not up to a two way discussion on the subject when not in a good state physically could have well hindered his recovery. He's certainly not a well man now after this latest set back.
