Love or hate??

what is difference between love n hate?
love come 1st or hate come 1st???
who believes d relationship start wit hate will be more better than a relationship start wit like each other??
who can make sure that a relationship tat the 2 persons who nvr know each other......
is diz relationship will stay longer than they hope?
do u ever ask urself be4 that wat is love??
I can sure that when I ask a pair of couples that wat is love.... they will nvr how 2 explaine it out...
but 1 more thing I can make sure is..... when the love turn into hate.... the person who hate another person that he/she love is more painful n hard 2 continue his/her life again..... it is more painful than a knife cutting along their body.... juz feel like a knife straight away cut it into the heart.......... tired..... reli tiring the life n soul.....
