Today during a Jelly king run I got mail from someone. It seemed very odd to me. See this photo and you will know what it says: http://cloud.steampowered.com/ugc/505763950861568284/588A78C343CD49BCAAE...
The reason it was odd to me because I do not recall getting a proto sword.
Any sort of reply that isn't trolling is appreciated.

Seems like at some point in the past you sent a mail to someone saying "Here is a gift" and attaching a proto sword. The attachment was never accepted by the recipient and after the mail was deleted after 30 days, the Spiral Postmaster returned the attachment to you, the sender.
