when love and hate collide

some of us treat friends better than family members. and why is that? with friends, u have a reputation to live up to and with family members, no matter what u do, 'air dicincang takkan putus', is that it? why the double standard? it's not ok for u to hurt ur friends' feelings but is it ok to hurt the feelings of ur family?
sometimes i question this myself...
yesterday, i did a free favor for dad; sent his car for car-wash. there was only one bench that can sit 4 ppl the most. there were 3 guys sitting without guilt, conquering the whole bench without even a slight glance at me, the pregnant one. the weather was so hot but i didnt complain. these are among the things that makes me nag about our ppl's self-centeredness. why the ignorance on their part? who do we blame? their parents? teachers? or perhaps the man in the mirror?
