Not every case of getting sick is a direct result of another not taking precautions, there are germs everywhere, in the bus pole, on your own furniture, everywhere, you cannot be exactly sure where you get a virus, maybe you involuntarily touch your face after touching such dirty surfaces. Germs spread everywhere all the time and it's not someone's fault, we don't control the actions of germs. I've realized that when something goes wrong people are inclined to irrationally look for someone to blame even though another person isn't the cause of it, that is exactly what people are doing in this pandemic by lashing out at people for not wearing masks and not social distancing, so much for "being in this together" people are like you are creating division. Maybe you should grow up and stop irrationally lashing out at others. A non-sick person minding their own business and not wearing a mask is not the cause of you getting sick so stop your childish blame game. https://www.google.com/amp/s/www.psychologytoday.com/ca/blog/fulfillment-any-age/201509/5-reasons-we-play-the-blame-game%3famp
