What do we mean when we say it today?
A lot has changed since those Shakespearean wayback days, but this phrase has remained the same. "Love is blind" has been said by men and women alike for ages.
And it's been used to say completely opposite things.
A girl might say "love is blind" meaning that she's got the hots for the wrong guy. It seemed great at first because the whole love thing made her think that. There were flowers, romantic dates, and a whole lot of excitement. All that made her think it was love when it wasn't.
Or, a dude might say this to mean he's totally willing to forget about all that annoying stuff his girl does because he loves her anyway. Aw.
Or, we use it in a not-so-nice way to refer to loving someone who is, shall we say, less than attractive. Love is blind because we don't care how a person looks. We care about their inner beauty.
See what we mean? This is one phrase that people use all the time. And every time, it can mean something positive, negative, happy, or sad. No wonder this phrase has stood the test of time.
