He’s staying overnight - that’s more than a routine admission.
I really hope he gets better soon, but if he is a lot iller than he’s been claiming why lie about it? It would be far more productive to just tell the truth. My distrust for him would just increase if he’s lied, as he could have actually used his own experience of covid for the greater good. Instead he’s let his ego get in the way of being honest, and his worry about being seen to be weak. He’s human, and he’s missed a chance to show his vulnerability as a human and that vulnerability could have helped out a lot of people going through this right now.
I obviously wish him a speedy recovery, as I wouldn’t want anyone to go through what he’s going through.
