Gender roles in society means how we’re expected to act, speak, dress, groom, and conduct ourselves based upon our assigned sex. For example, girls and women are generally expected to dress in typically feminine ways and be polite, accommodating, and nurturing. Men are generally expected to be strong, aggressive, and bold.
Every society, ethnic group, and culture has gender role expectations, but they can be very different from group to group. They can also change in the same society over time.
