Phew, I'm back. All work and no play makes Jack a dull boy. With that spirit in mind, here's a game: I'll show you a few pictures, and you tell me what's wrong.
If you guessed that letter "A" does not fit in box "B" without violating the printed instructions, you win a cookie. Yes, it's the fine art of letter folding, brought to by the United States Postal Service. Either being literate in English is not a job requirement, or giving a damn is optional. Thankfully the contents weren't damaged by the mishandling or I would have had to go postal.
You'd think with the ability to place this particular envelope in the larger box on the left of picture #2, they would have actually done so.
I had this experience a couple weeks ago as well. I received a diploma for joining NSCS with the same "Do Not Bend' instructions on them. Alas, it was placed in the smaller box bent all to hell, instead of placing it in one of the larger parcel boxes and leaving me the key. Bah!
Mind over Matter, my son. Mind over Matter...
