Who's here?

Who am i really? An imaginary being, like the square root of -1.
O, and u2? No wonder we get along so well together!

We tend to push our way along, with the illusion that while liberally whispering, smoothly saying, and shouting messages back and forth at will, we are effectively communicating, though we are by and large oblivious to our frequent backfires, misfires, and blanks.

— Floyd Merrell (1997, 244)
