The sentences that use the second person point of view are:
"Unfortunately, I decided to ignore the clouds and move ahead with my plans. Later, I asked Cheryl what she would have done but she just looked at me, shaking her head."
"Unfortunately, John decided to ignore the clouds and go forward with his plans. It is easy to judge his decision from this vantage point, but put yourself in his place and think about what you would have done."
The second sentence specifically addresses the reader directly with "put yourself in his place and think about what you would have done," which is a clear indication of the second person point of view.
