We had mail delivered and the lady brought it up to the door. No mask on. My mom was home, she is 80 year old, and opened the door and took the mail and needed to get $2 and some odd change to pay for a package. The post lady stayed outside but she should have been wearing a mask if she was going to interact OR stay at the bottom of the deck. Very very carelss! If my mom gets infected, it could have been possibly from her! Please stress the importance of wearing a mask!!!!!!! Thanks, Bonnie
