Lebanon, is it true opposites attract?

i dont get why people always say opposites attract, i always see same type of people ending up together, spoiled up your azz people always end up with spoiled up your azz people (cough cough my sister and her bf, both loud and spoiled, but both also ambitious and he is rich), stupid low cl people always end up with stupid low cl people, i never seen like a harley davidson tattooed guy married to a woman from the WNBA, now that is opposites attract........
