Last week I made an economic exchange that was not entirely rational. I paid people at Tufts University's small-animal hospital US$4,000 (S$5,400) as a deposit on an estimated US$6,000 medical bill. This was for treating a cat that, six months ago, nobody wanted.
Nobody except me, and back then I wouldn't have been crushed if someone else had taken him and I had to choose a different cat. But nobody did.
