when u see a really nice pie, and u're not allowed to eat
it.
u say, "nvm la, see and smell only, no harm", then after a few
mins, u say "hmm, maybe a lick won't hurt" then after a few mins, u
say "maybe i just nibble on the crust a little bit" then "maybe
just taste abit of the filling of the pie"
then after awhile there's an ugly small hole, so you say "hmm,
aiya, so ugly, lets cut a small slice la. to make it look more
pleasant" then after eating that small slice you say "aiya, now
hungry liaoz.. since cut one small slice liaoz, wats one more small
slice?" as it goes on.. u finally found out you've eaten the whole
pie
