Nothing to Write

I can't think of a single thing to write. So I'll tell a math joke:

An asymptote is driving a friend home after spending a long night drinking in a bar. All of a sudden a siren blips and his car is filled with flashing red and blue lights. The asymptote calmly pulls over, rolls down his window, and causally leans back in the seat. His friend, amazed at the asymptote's level of calm, asks, "why are you not panicking right now? We've been drinking for hours!"

The asymptote looks at his friend and says, "I know my limit, and I'm approaching it, but I'll certainly never get there."
