    Yes. In other words, let me spell it out, cause some need it spelled out. When the letters are stuck at the USPS, only one has access to it, and there are no witnesses. What happened that now, witnesses are needed? I sent it last week . . . we didn’t get it . . . I sent it again . . . we didn’t get it . . . You ready to go out to the mailbox? Yeah, I’m ready.
