their mood fluctuates de 
like today's argument started when i said i refused to buy a lock
for the car, because my car already has two in built lock, they
wans me to get another lock to lock the stereng. last time we used
to have one, but last weekend it got stuck and i spent nearly 2
hours and extra rm 20 to get it unstuck 
so now i said no need to get another one, they unhappy and said i m
being stingy, but i dun see why i shud fork out money for something
i do not need.
