Does opposite attract???

i've been thinking about this question for quite some time. Does opposite seriously attract like magnet where the north will always attract to the south... does the same theory apply to human relationship as well.... well this question not only applicable in boy and girls relationship only, but in all type of relationship such like friendship, family love, and many many more.... well for me, i feel i will give around 70% agree to the question above... why?? cause its show in my real life..... all my friends.. close or normal all seems to have the same figure that is tall, quite outgoing, and many many more which sometime i feel quite different from me... this include my penang and sabah friends..... i once found a person, who more or less same like me, the quiet type, but after a while i feel hard to be with... why??? i have the same personality too so how come i feel hard to be friends with her?? and i've been wondering till now..... could it be its more interesting to know the life and personality that is differeent from yours or could it be you are curious with a personality that are different from yours and this invoke your interest to understand and know about it.... Could it be??? well friends, i have put a poll on this question and i hope you will at least answer it so i can have a more reliable answer ..... thanks..
