Hop over to Mark’s blog where he gives (a rather long) analysis of “how to fall in love”, including the inimitable Cochroach style or the Mosquito plan:

The uncertainity theory clearly states that it is impossible to claim, with 100% confidence both the state and level of desperation of a person. That is, the surer we are about our percieved singularity or duality, the less certain we will be about our level of desperation. Therefore, the truly single or dual person tend to live in ignorance of their own despo status until external realization dawns in, muddling the clarity in their status.Further, extreme duality may be associated with a nagging sense of foreboding, and a total loss of individualism. The terms could further be extrapolated to single-dom, though a specific dual-dom does not exist.
