The Crazy Ivan

In one of the best submarine movie of all time, "The Hunt of Red October", when the captain of the Russian Submarine (Red October) was about to defect to USA, another US submarine found Red October and followed it in its blind spot so it cannot be detected. However, RO suddenly made a few extreme turns, making the USA submarine very nervous, thinking they were been discovered, Jack Ryan the main character told the captain of the USA ship not to panic, 'cause Russian submarines are known to make crazy turns to make sure there is no ship following them. They call this dangerous maneuver, "Crazy Ivan"

I told this story to my friend when he was commenting on how girls in seemly stable relationships will sometimes want to "think about" their relationships all of the sudden, or they want to have "breaks" all of the sudden. All of sudden, out of blue, no fights, no arguments...

They just want to check if guys are still following them, just want to make sure they are still in right places.

So, like a "Crazy Ivan", there are only 2 things you can do, keep going and ram into the leading submarine (the girl), or shutting down engine and sitting idle. In the movie, they shut down the engine and wait for Red October to stop the "Crazy Ivan" and continue the course, and I suggest my male friends to do the same...
