selfish = sell fish?

selfish... yea... is refering to the chiefly thinking of one's own need and welfare without care about others. and of coz we r all selfish too.... just the level of selfish-ness is totally different in different way and in different things. some of the ppl really really just think of themselves. when unfortunately meet this kind of person... the tolerance is needed... how? just keep quiet? talk to them nicely? shout to them loudly? if just keep quiet... can stand until when? sometimes, we do need to think of other person also.... since other people also do the same thing to you... help u when u r in trouble, help u when u r not around... m i rite? in a nutshell, how you treat others , then people also will treat you back at the same way.
