50%

In some cases, 

we have to accept how some people acted and behaved 

not how the person should act based on our point of view..

In any relationship, we share the responsibility. 

50% each...
if we've done too much until we can't stand with it any longer, 

then.. no need to put so much further effort lah.. 

just ignore tak perlu pikir banyak

and
if we have put too much effort in thinking, keep thinking and thinking
tapi tak paham2 jugak note epidemiology ke hape ni ntah..
then just ignore tak perlu pikir banyak..
dah cecah limit 50% of responsibility...
another 50% nasib lah soklan exam esok tu susah ke senang bleh jawab ke tak..
ok bye!
