We're having three friends over for dinner tonight. All of us have gotten our second vaccines weeks ago. None of us are ill. My wife says we're eating outside and the guests won't even come in the house except to use the bathroom. I don't understand -- what was the point of vaccination, then? Why are we living in fear? At some point, we have to just bite the bullet and get back to normal, in my opinion.
