They cough and sneeze and be all snotty for a few days and then they're over it.

It was funny like a year and a half ago my son had to stay home from preschool because he got COVID so he stayed with me for a few days and coughed in my face for a few days and then I got a stuffy nose for like two days. That was all that COVID did to us. Washing your hands and hygiene shit like that is smart, but the most important thing is to support a healthy immune system.
