Does Your Secure Mail Seem Like a Red Flag?

I hate getting mail that is "Top Secret" or has "Important Information" stamped on the envelope. I always get nervous when I see these letters in my mail box. "Top secret" usual means a bill I forgot to pay or a pin number that I am paranoid somebody already has.

It seems like it might be safer if these important documents weren't stamped "important" because I think you're just asking for someone to steal or open them if it is marked "secure information". It makes me nervous.
