Weird theory???

~today, my classmates told us a very very weird theory of the nature....
~i never hear before and thats why i felt so interesting with that theory and start listening to my friend....
~JIN said: we identify something but we don't recognising that thing....
~oh my god, what a big question mark turning around inside my limited brain....
~i can't get what he trying to say...
~so, i ask him to give me an example on how the theory work???
~end up..u know what example he gave me???
~lets look at this...."i identifying you as a female but i don't recognise you as a female"
~what this mean leh?? -------->i m not a female....i am "BROTHERS"....wakaka...
