The Labyrinth of Applied Math

I was sitting in Applied math, and the topic was kind of hard. So at some point I had to wander in the window of my mind! So I looked outside the window, and I started to think that if someone looks at me at that instant and think for a moment about what I'm thinking, would he/she possibly think that I am thinking about what they are actually thinking about me which is actually me thinking about there thoughts?
