Once there was an international poll and Malaysia was high-ranked in the list of rudest countries. The ministers retaliated by saying that no, Malaysia is the softest spot in the Asian Pacific map.
Unfortunately, we are rude.
Just take your car out to the road and you'll see why. It is a battleground out there. No wonder the road is one of Malaysia's successful population control scheme.
Politeness are only for westerners and sometimes they had to be Caucasians.
p/s: I hate it when people have broken tail lights. But being so Malaysian, I have never bothered to check mine.
