dm and his wife clearly have too much time on their hands. If my two-doors-down Iranian neighbors are Muslims and their religious decorations "infringe" on the public sidewalk, I'm not going to write them nast-e-grams, I'm just going to walk around the decorations. Similarly, my Indian neighbors across the street have religious decorations ...
Granted that the neighbors, if they wrote "Merry Christmas" on the package, were ungracious I suspect dm's wife's nast-e-grams were far less gracious. But let's pretend dm's wife's notes were so gracious as to include being scented. Writing "Merry Christmas" on their package is a proverbial "Federal case"?
"a package from amazon"?! Last I heard, Federal Postal regs don't apply to private delivery companies' packages.
