sad by thinking

now got bunch of frens going to leave mmu ady...
kind of sad when every time think about it.
no matter is my senior, my batch frens, my best frens,
a lot of them going to grad already...
going to leave for the future life,
now i think about that, is it worth it i know so many ppl..
if i not know much if them, then my heart will not so pain.
when i remember back how i know them,
my feeling can be said hard to describe,
seeing 1 follow by others keep on leaving,
and dunno when is the time to meet up again,
is totally sad... hard to bear it...
why i cant be selfish to think about myself only,
why i need to care more to others compare to my own.
why why why...
this is the thing that i dunno about it. why.......
