I feel like the next natural step would be for each household to combine with another. Keeping mingling between two or three households and introducing more slowly ... maybe once a month. Until a vaccine or cure is plentiful.
Meanwhile I dislike taking the Sam (the dog) for a walk. I’m constantly crossing streets or changing direction to avoid oncoming pedestrians. It’s like a big zigzag dance. We need to make rules .... walk on the sidewalk in the direction of traffic... I think that would at least help. I read somewhere that that’s how they “do it” in Europe but I have no proof that it’s true.
