People sneeze, cough, clear throat, and if having bad day runny nose teary eyes and cover nose and they would say what's that smell.
There are people that sneeze all the time my husband is like that at first I thought it was me but he actually had to come home early because he was sneezing so much at work. My mom when I talk to her over the phone always coughing and sneezing.
I know it's allergy season in the east coast and it's so difficult because you do not know if its you or people have allergy.
