Opposites attract.
People with dissimilar temperaments are said to be drawn to one another.
What They Mean
Difference is interesting. The qualities you lack look charming on someone else, at least from a distance.
Are They Right?
Initially, yes. Novelty is a powerful recruiter. Long-term outcomes depend on whether the opposition is in taste or in values, a distinction the saying declines to make.
What They Left Out
Opposites also repel, argue, and negotiate thermostat settings for decades.
