Hype and tripe. I read anything for a million US dollars for HK$ forget it, stick it in my mandatory provident fund.
The weather a lovely subject to talk about, everyone does it. Though in Hong Kong its maybe not such a coomon practise. I always start with, "isnt it a lovely evening....etc" and people look at me like is he on happy pills or what! Maybe locals dont have time of day for such stuff.
