just 4 factors... and we have 16 permutations. imagine the permutations of greys if we include other factors such as dress, talk, think, sexual organs (possess one or both), la la la... and of cos there is another totally 100% set of permutations possible when we include the perspective of `perceived as'. this is indeed a very grey world! or rather, this is a very colourful world. yet the rules defined so clearly in the monotones of the two extreme characteristics of those in the first and last line... sad!
