Addiction or Fascination

I've often wondered why we Bangladeshis or Bangalis have this fascination with rooftops. We differ from westerners so completely in this facet of life. To any foreigner, going to the roof is like a chore. But, to us it's like one of the coolest things ever. We love going to the roof. Going to the chaad as we call it seems like a great idea to us, whenever we may be presented with it. "Cholo chaade ghure ashi" is a common phrase that we all have heard so often from a friend or cousin. It's like whenever we don't have anything to do, we just all go to the roof. And not only do we just go to the roof, we act like it's one of the greatest adventures in the world. There are exclamations about how the batash is joss and how the view is just too beautiful. Hey, don't get me wrong here. I'm not against chaads in any way. But I'm just curious about why we love this so much. I mean I get excited every time I go to a friend's rooftop... it seems so cool to me. But I don't know why!!! So... people, if someone out there can help me, please, enlighten me.
