So many fans these days...

No, not fans of my work, I haven't got any of those, judging by the numerous emails and comments I don't get. The fans I'm talking about are the chinese-style folding kind one uses when the weather is hot. And while I do realise we're in the middle of another heat wave (how could I not realise it when I'm not comfortable when it's over 25C...), it's the first time I see so many people using those fans. Is it because I wasn't using the Parisian metro during past heat waves (I haven't spent so many summers here these past years)? Or maybe because I wasn't attentive enough? Or possibly I have simply forgotten... Or is it really a new trend this year? And if so, is that the sign of a new orientalist trend?

Could also be that the heat is messing up my mind...
