Thanks to each of you who responded to my post with your own masking experiences that validated my own. Medical staff in healthcare settings should be in the vanguard of protecting vulnerable patients' health by wearing a mask when they are caring for them. Many are vulnerable to infections due to immunosuppression, illness or simply advanced age. In the meantime, I plan to continue to mask, and if a care provider does not mask, I will politely ask them to mask. Please continue to post your own experiences or opinions about this.
