Equation again?Noooo~

Let x and y replace the level of boy X and the level of boy Y on Z

For the time being:
x=y

But,it may become either:
x>y

or

x(less than)y
Still,under SOME Circumstances:
x could even be zero!
because Z will be like so fan!!!!!So sometime,you need to......
for the sake of your....lah!

My life will be,is tough,anyway,cause it's destinated to be...
Hope for the best,prepare for the worst
Hope that I'm not the x(less than)y

P.S.the less than symbol interfered with the HTML so I couldn't use it,sorry...
