Economics

I love the way umbrellas are suddenly for sale everywhere when it rains. And I don't mean in shops. On street corners, outside buildings ... anywhere you could want one.

Just the other day, it had started to rain while I was on the bus, and I had neither an umbrella nor a raincoat with me; when I got off the bus, there was someone to sell me an umbrella -- almost as if they'd been waiting just for me!
