After forty years of abuses under the communist system, the Polish people are very protective of their privacy. They do not want any private information revealed to anyone
That's interesting. At my first apartment in Wro that I shared with another guy, one time he was in the shower and the mailman came with a package for him. I told the mailman that my roommate was in the shower and I'd sign for it, but he wasn't having any of it. He made me get my roomie out of the shower before he'd ever let go of the package, which at the time seemed a bit overboard, but now kinda makes sense. Huh.
