My wife daughter and I wear them anytime we leave the house. Work, grocery shopping, daughters volleyball games, everywhere. Even when there are countless others walking around with no mask. We don't wear them to keep from getting the virus, we wear them just in case we are carriers of the virus to not spread it to others. In theory, if everyone wore a mask it would stop spreading. It's the people who don't wear then and are carriers spreading it. We could still contract the virus even wearing a mask. Its sad that not everyone is willing to do their part to lessen the spread.
