FMyLife in Differential Equations

Today I was sitting in my Differential Equations class, taking notes as usual. The professor was just making a really good point, saying that Fourier coefficients were actually the terms of a series of trigonometric polynomials in a L2 metric space, coupled with a measure of distance that he had just defined. It was an interesting point and I sat back and put my mechanical pencil in my mouth. I didn’t notice that I grabbed the lid and when I took it out of my mouth to continue writing, all of the leads fell out and went all over the floor. FML.
