Why is my neighbor thanking me?

We talked across the fence -- and well more than 6 feet apart.  My neighbor works in health care, and she is thanking me for staying home.  If we can contain the spread of coronavirus (and even flu) by having people stay home where they are not exposed, it will make her job safer.  Both of my daughters-in-law have sisters who work in health care, and Mary Beth's Mom is a nurse.  Not only are we protecting old and vulnerable people, we are also protecting health care workers.
