Far from it. If you think at risk groups are comfortable in how they are having or choosing to live their lives, you are mistaken. Some people take risks because they have to, not because they are comfortable in doing so. I am not particularly considered in an at risk group, but feel very uncomfortable amongst the general public, whom, imho, many seem to behave as if covid is no worse than a cold. We shop online, we take it in turns to go to supermarkets alone at quieter times to avoid people getting up close and personal reaching across for a tin of beans or looking at us oddly as we hang back whilst they linger at the Yoghurt isle, picking up and putting down several potentially infected germs on the numerous packs before deciding not to bother and getting a Panna Cotta instead.
Life would be safer and simpler if people pulled together. If ever we went to war or were invaded, i reckon this country would capitulate within hours.
