Thank you! I mostly agree with you, but believe it's incorrect that the Post Office does not care about and never pursues mail fraud on "small" matters such as soliciting and receiving money for purchase of Priority Mail postage and choosing to keep the money instead of mailing as promised or refunding. I am also aware that they also make themselves concerned about use of the mail to obtain property or money by fraud, but the postal money that was defrauded is, if I had to pick one, perhaps the bigger to them. Where there does become a question is "willful" or intent. The failure to return the knife could arguably be procrastination rather than willful fraud, but the continued keeping of the Postal money is, at this present moment, a willful choice demonstrating intent to keep and therefore I think is sound fraud evidence. We will see if the Post Office agrees.
