It seems as if chayav is asking this question because he hears around him people saying how bad it is and that they don’t go. I assume he just wants to know WHY.
When I was younger we always went to the movies, the school didn’t like it but they didn’t forbid it. Once I was applying to high school they forbade it and ever since then my family hasn’t gone. I always figured once I got out of high school ill go, but I didn’t. You see things differently once you grow up.
