A friend is a variable in a function(One's timeline representing the change in friendship with the change in variable.) representating it's dependence on variable .....For different values of variable the function value changes ...But it's also true for different nature of variable the values of function changes......If both function and variable has positive value -"they r associated"...If they have opposite signs "it may associate or dissociate" n if they both r negative" it's dissociative"...Yet another case remains....What if the function becomes independent of variable,I.e, a constant!!!! Simple- "Astala vista variable (frnd)".....
