Don Brown has been driving a school bus for more than 20 years in the Chicago area. And for all that time, he's noticed one odd student habit.
As they climb aboard his bus, "when they get to the top step, they always cough," he says. "This was even before the pandemic! Or, when they get ready to get off, they say 'Bye, bus driver!' and they cough."
Because of this, Brown says, he hopes he'll be getting the vaccine, "as soon as I can."
