They think we are spreading covid around. I tend to distance myself to anyone hacking sneezing & coughing too, long before covid, I don't need to catch a cold.Bummer to hear allergy shots didn't help you. They were life-changing for me.
On super annoying thing about being in the middle of an allergy attack is if you literally have to go somewhere it can get awkward because people assume you're sick and look at you like you're really inconsiderate.
