@RidleyDM @DrLeanaWen That aside, I really don't understand why you have a problem with the concept that people see a situation that is out of hand, and believe that everyone should be wearing a mask to help, but individually doing so won't make enough difference to motivate individual action.
@RidleyDM@DrLeanaWen撇开这一点不谈，我真的不明白你为什么会有这样一种观念，即人们看到一种无法控制的情况，认为每个人都应该戴口罩来帮助，但单独这样做并不能产生足够的差异来激励个人的行动。
