I think Jon is plotting to take over the world.
Yes, the entire world.
You see, normally Jon reads fiction. Things like Tom Robbins and Junot Diaz, among, many, many other innumerous authors. Then things suddenly changed. A couple of nights ago we were both in bed reading our respective books and as I start dozing off I read the header of his page “Supernatural Numbers.” My mind quickly started turning, “Why is my husband reading about Supernatural Numbers? Muy strange…” And then, the next day in the mail a book arrives that he ordered. Its title you may ask? “Discrete-Time Signal Processing.” Ummm, yeah. What the heck is going on?
