need to figure out this mind first..

but somethin i've been thinkin bout..conditional love vs. unconditional..if u think about it... its actually a much harder concept to grasp than u'd think.. we all like to think we love unconditionally..but really,how many of us would keep on loving someone if they did not return that love?ie. with friendships,would u keep on 'giving' even if the other person is unresponsive/doesnt seem to cherish the friendship as much as u do?? am i mixing up two diff things here? i dunnnno.... but i find it soo hard to do. it's not impossible tho..a mother's love towards her children is unconditional..my baby cousin was born earlier this yr..and he was unable to do much except eat,cry,sleep..but my aunt continued taking care of him even when he refused to eat and woke up late at night crying.. or even with my mom..i get angry with her n stuff,but she still makes me lai cha n oatmeal for breakfast like she usually does..she doesnt haftu do it..but she chooses to love me even when i 'gick' her(make her angry) or make her worry bout me..
how dooo they do it?!
