This isn't a question, more an anecdote to share - I haven't got anyone who would appreciate it the way folks here might. And it seems the red amulets are coming up a lot at the moment...

About 5 weeks ago I asked a question about a nail becoming tarnished within a day of having it in the salt-filled red amulet. It freaked me out that it happened so quickly - JMG said tarnish was OK but not rust. Well within a few days it was definitely rusty and even starting to corrode. So I changed the nail (& salt), and changed it again when it rusted just as fast a week or so later...
On NYE I swapped them out again for the fourth nail in a month, aware that I would be spending time in the presence of the person I suspected of sending the bad energy. But I felt something shifted with that person that night... and over a week later the nail is still bright and shiny! So bizarre having the salt and nail out of the same packets on the same person under the same physical conditions but it reacting so differently...
I was skeptical at first but now fully convinced TSW!
Thanks again for the red amulet suggestion, JMG.
