Are you intimating Boris was so astounded at Trump's comments he sat there open mouthed ? Like the rest of us ? Or in fits of laughter I should say !
I'm intimating that unlike the CCP or Boris, Trump might actually value the lives of his citizens more than their us dollar tax receipts, so he told whatever scientist suggested herd immunity to go fuck themselves. Boris isn't a billionaire, will never be a billionaire, and sees those uk sterling tax receipts as his ticket to at least scraping onto the millionaire list... so herd immunity, then shamed into silence/hiding.
