 Re: looking for an idiom
Someone already said "Birds of a Feather Flock Together" ... that is the only one that I could think of ... but it generally is used to refer to the selection of friends, rather than romantic interests.
Usually in the USA, we suggest quite the opposite for those romantically inclined when using the idiom "Opposites Attract." Meaning that we look for partners that fill in our blank spaces, or our complements. Rarely do we have sayings between men and women that highlight shared traits; we usually highlight and exaggerate the differences; such as "She'll get him today; but, he'll get her tonight" ... speaking of the wedding day and night.
It is interesting to take a deeper look at how discrimination plays a strong hand in our informal language. Embedding "isms" inside of idioms makes it more culturally palatable to maintain unattractive institutional assumptions. Of course, we do the same with jokes. Societies have all sorts of gimmicks to enforce and maintain the status quo.
One idiom that I can think of for two people marrying outside of their class status is "Marrying up" ... which tends to also have a negative connotation.  |
