Work-hubby the other day lamented the fact that he took the vax. The first one. But not the second and absolutely not the "boosters".
I felt bad for him as we were still WFH then (floor construction), so our inter-actions were severely limited, and his parents and Dr and friends had a bigger influence on him than me at the time.
THOSE are the people I sympathize/empathize with. Those who thought they were doing the right thing, but now regret it. But there is no turning back. And I told him that it sucks he'll die of a heart attack by 60 - I'll miss him.
