A weather musing

I was reflecting about.. rain being seen as a sign to ‘do nothing’ in Chennai. Life, in general, used to stand still when we were faced with a few days of rain. Roads would flood, schools would give us a few days off.. and of course, it was perfectly okay to feel lazy when it rained. Rainy weather was perfectly gloomy and seemed to call for nothingness.
In Singapore, it was slightly different. Being tropical, rain was more common. Back in university though, rainy weather was still seen as a nice excuse to sleep in late. As it rained pretty often, I guess that tells you enough about regular attendance in classes.
I wonder what the excuse is here in London. Since it is practically grey and rainy all the time, there’s no way rain can be associated with lethargy. Maybe it’s the sun?
