so 2 of the places I get "souvenirs"  from require a signature for delivery. at first thought it was spooky weird then I thought " what better way than to be obvious! well it's not, to them anyways. just an important signature letter to be delivered.

thought I would toss that out there. helps if you know your postal people on a "hello" basis too. better if you have bought them a beer if you live someplace smaller, you get the idea. they maybe looking for sneaky and not some official signature required post. signature will mean they can't outright steal it and it sounds like someone is watching your box without official notice. 

sounds like someone scored your seeds. or tossed them because, well you know, the voices told them to.
