hahaha.. scare wat? u are lao shi ok? 
anyway, there aint many nice & friendly ways
to reject ppl, esp when u are dealing with those who knows how to
take advantage of others.
the subtle method i normally used are to be less effective in
helping them. one of the reasons why they approach u in the first
place is either because they think u can do it well or u had done
it well.
so... just take ur time in whatever they asked u to do something.
claimed that u are busy with something when they asked, even though
it wasnt the truth.
i rather be named ineffective than to be known as mr.
robert.
