I just signed on to do a web search to see if there is any meaning to finding wheat bread in the mailbox!  I just found a few slices on top of my mail from yesterday when I went out this morning to pick up my mail. It is an ordinary mailbox with no locks or special devices to prevent anyone from doing this. I was curious if someone was sending some kind of sign. Should I worry? The replies here and what I found have me more nervous now! Yikes!  Any serious thoughts or information about this would be appreciated.  This site came up on my Google search. I am gonna keep trying to find some answers.  Thanks to all for your help -- if there is any to be found on this subject.
Best,
Nick
