<prompt> Human: My mom sent me a birthday card in the mail which I didnt receive until a month after it was sent. When I received it , it was in a sealed bag from USPS indicating that the card was damaged. There was an opening at the top of the card which appeared to have been opened with a letter opener and of course , no money inside . I confirmed with my mom that she sent 100 bill. Is there anything that I can do at this point ? At least make the PO aware of what may be taking place in their sorting facility ? Myself and my mom have learned a valuable lesson. Never send cash through USPS  <response>: I read an article about a lady that stole over 1000s from peoples mail before she delivered them .They caught her by sending money and tracking it on her route where the money goes missing
