Teoria i praktyka

Moja dawniejsza dziewczyna (och!-jak bardzo dawniejsza :-) ) po rozstaniu i po latach - kiedy dowiedziała się, iż zdarza mi się pisać również wierszem - zawyrokowała, iż muszę być człekiem głęboko nieszczęśliwym!

Nieszczęśliwym!
Ha!
- Kiedy właśnie znalazłem spokojną przystań u boku wspaniałej, pięknej Żony a Dobry Bóg pobogosławił nasz związek równie wspaniałym Synem.

Zapewne wyroki ludzkie biorą się z własnych doświadczeń, a być może wybranych lektur, ale zapewniam, iż należy podchodzić do tego z pewnym dystansem i badać ich "jakość" -jeżeli to możliwe - losami... wyrokujących. To da lepsze efekty niż bezkrytyczne przyjmowanie ze względu na nazwisko czy pozycję autora.

Nie chcę przez to powiedzieć, iż to stuprocentowa reguła, ale...

PS. A przy okazji-i z okazji kolejnych swoistych kolejnych "wzmożeń" związanych z lekcjami religii w szkołach.
Mamy już tzw. swoje lata i pamiętamy jak to bywało za rządów budowniczych ustroju zwanego komunistycznym czy socjalistycznym.
I dlatego wciąż niosę, nieśmy, pamięć o tym, iż szatańskie działania jeszcze nie zostały zakończone. I nadal znajdują ofiary wśród nas-ludzi obdarzonych ciałem, rozumiem. I duszą!
Nieśmiertelną!
