y bear grudges? haiz... dun like dun come lor. people who bear
grudges are people not only have not grown up but people who are
too tired of living and funny how, they never get sick of
themselves doing these over and over again... 
mathematically,
if bear grudge = sick of life,
sick of life = tired of living.
hence,
tired of living = thoughts of death
in conclusion,
thoughts of death = dying
dying = kill yourself
he must as well go hang himself?
