We should try, to best of each of our ability, to behave in a responsible way - especially during a highly contagious, global pandemic. No one is asking you to do calculus, only to wear a mask. Like you wear a shirt. Like you wear shoes. If we all wear our masks: the disease will not be able spread as easily as it is now, and will come to an end sooner. If we refuse to do our part to protect each other: more people will become infected (including some that you may love) and we will not see the end of this as quickly as we want. We're trying to have a functioning society here. Let's not be lizard brains, shall we?
