IF a person dislikes "x" things in life.

Then "x" is a function of "n"...

where "n" is the serial number of that person with total "max(n)"=population of earth

xn = f(n)

For two people there can be three possibilities :

1) x1 = x2

[Greatest chance of mutual understanding (mu)]

2) x1 "intersection" x2 > 0

[Lesser chances of "mu"]

3) x1 "intersection" x2 = 0

[Least chances of "mu"]

P.S : We can never be definite, thus the use of word "chance"
