Answer:
In everyday behavior, men are less likely than women to smile at others.
Explanation:
Women and men can have very different personalities, not for biological reasons, but for environment and behavior. Generally speaking, researchers have found that in everyday behavior, men are less likely than women to smile at others. This is because we live in a patriarchal society that taught that men should not show sympathy but maintain seriousness at all times. Women are taught to be friendly and to show it to people.
As has been said before, this is widespread information and does not mean that all women will smile and be nice to everyone, nor does it mean that all men will be serious and will not smile at anyone. It depends on one's personality.
