Wear a sodding mask! It's not all about you! If you don't want to wear a mask to protect yourself, then do it for others who are less robust than you. There are people out there fighting pre-existing conditions whose lives are already a struggle. The last thing they want is to contract COVID-19. If they do, the probability is that they won't survive it. Do you really want that on your conscious? Is that really YOUR CHOICE? So, get over it! Wear a sodding mask!
