My mom rocks, too. She bursts in laughter when watching Kill Bill or Terminator. She considers Schwarzenegger's movies some of the best comedies she knows. She loves Blade Runner and 2001. Occasionally she eats some university lecturers alive in courses about cultural and anhtropological and sociological things although never have worked herself and having no job education herself. She spends hours per week playing Unreal Tournament. She is curious at everything new. Her bookshelves are filled with books, in parts academic literature she found herself, about almost everything you can think of - she reads that stuff and considers that "relaxation", like I read novels. She's 62 - and although I know her since 43 years now, she still can manage to completely stun and surprise me.
If you, at some time in the past, should have thought that I am crazy - wait until you meet her!
It's great to have very young parents (my mother was 18 my father 22 when I was born). You really appreciate it once you have grown up yourself and realise your parents are no old, grey mummies already, but still are at the peak of their active lives, sharing adult life with you.
