I hope nothing happens to your Mother. Mine died at 95 in Jan from natural causes before this shite started. We were careful for years, about visiting her when we obviously had colds.
You used common sense. Unfortunately, there are a lot of people that just don't get it. A simple thing like not going out in public when your ill so you don't infect others, parents keeping their kids at home instead of sending them to school or the day care to protect other kids, washing your hands before you eat, washing produce, washing down your counters, disinfecting door knobs, etc. Not saying every single day -- but germs happen!
A lot of these procedures are being touted as a way to fight this virus -- most of these practices we should have been doing already -- especially with it being flu season.
But it seems people are now alarmed and 'inconvenienced' that they need to cover their sneezes, or coughs, and certainly try to avoid being around sick people or don't go out when they're sick. Duh. People, what happened to common sense and courtesy?
