so imagine that all the characteristics of a girl can be quantified in plain yes/no questions, whose answers can be represented with one bit each. thus, a girl can be described with a single binary vector, say N qualities condensed into an N'hFFFF...FFFF value.
some qualities are supersets of others, like "is a good e-mail correspondent" encompasses more specific qualities like "responds promptly," "writes interesting shit," and "changes the subject line to something witty."
now, if the top-level quality is already a negative, it completely wipes out all the other values, (given the above 4-pronged example) resulting in a brutal level of 4'b0000 instead of possible (and better) values of 4'b1010, 4'b1101, etc.
and that is quite disappointing indeed. if you imagine that a girl has this huge possible binary expansion, all these paths to an exponential number of leaf cells marked "1," a high-level negation blocks off an entire branch of goodness, pruning the tree into a stunted lopsided mass.
funny thing is, upon first meeting someone, i give the person a benefit of the doubt, a full 2^N tree, if you will. and the more i get to know them, the more pruning i have to do. it's not something i find enjoyable. you'd think that it would be more positive if i started out with N'd0 and worked my way up. it's all about perspective, right?
