I feel like I am writing something ridiculous, but it's not uncommon for an unmarried woman to wear a wedding band to preempt advances by men. Could we have a world where unmarried men who are concerned about being perceived as making an advance will wear a wedding band to send a signal that they are not interested in the woman they are talking to? (obviously some/many married men make inappropriate advances but perhaps this helps somewhat?)
