@TRyanGregory sorry to see you’ve stepped away from Twitter. There’s plenty of us who aren’t purists (I have a little one so we can’t be 100% covid safe but we, like you, try our best. FWIW, we eat outside too, as we try to balance giving our family as normal a life as possible , whilst trying to stay safe. It’s a minefield! Please consider coming back when you’re ready. Lots of us appreciate your thoughts.
@lucystorer Having kids adds another level for sure. Constantly making risk-benefit calculations, which includes their emotional well-being as well as their health. It's very, very hard to do. I appreciate you doing your best.
