Whenever one of my grandmother’s or one of my grandmother’s sisters’ knees would hurt, we would always say that it was gonna rain the next day.

The interesting thing about this story is that every time her knees did hurt it actually did rain the next day. Sergio says that he can’t remember a time when her knees would hurt and the weather would be clear the next day.

Another friend of mine, Katya, who is a swimmer and had surgery on her left knee, once told me that when it is about to rain her knees also begin to hurt. She says that during her surgery they had to put a screw in and that the metal may have something do with her ability to also predict the rain. Perhaps the change in magnetism affects the metal in her knee somehow. I asked Sergio whether or not his grandmother’s sister ever had surgery on her knees, and he told me that she never has had surgery but that she does suffer from moderate arthritis.

Sergio also says that his father doesn’t trust his mother’s sisters’ knees because they haven’t always predicted the weather as accurately as Sergio remembers. Before Sergio was born, his father said that on various occasions her knees would hurt but nothing would happen after. Thus, he came to distrust her “powers” of foresight.
