At one of the houses near my mom's land, there is a pond. Back in early 2010, before I left for Korea, the owner of the pond put two young white ducks, a male and a female, in his pond. They were young, and they grew up together, and they always swam as a pair. Mid-March of this year, a wild male mallard decided that he wanted to live in the pond. (We asked the owners - he showed up all on his own.) Initially, he could be spotted swimming after the two white ducks, as they did their best to avoid the interloper. Then something happened: the girl duck ditched her long-term male companion for the sexy, green-headed mallard. For several weeks girl white duck and mallard swam together, while white male duck moped off by himself. Then last week male white duck disappeared. Did he die of a broken heart? Did he leave to find a new pond with friendlier female waterfowl? No one knows.
