I actually had a run in with someone today around this. Started coughing all in front of me while walking near him, so I dodged around him, he got all defensive and offended. I’m like to him, dude, your the only coughing all over me! I don’t want this stuff thanks.
Some people are weird. I’ve had a similar run in with mothers and young kids who are coughing and spreading germs, people get all grumpy and angry when I make a point by moving away or giving ‘the look’. I’ve got better things to do than sit at home crook from some disease for a few days!
