Humans have emotions. This is our way of expressing our feelings and moods. So, why do an abundance of people display their emotions differently? What would be acceptable in today's society?
It's simple: emotions are not attributes that a person gains at birth. Emotions are learned behaviors that are taught to them as small children. This means emotions are picked up by parents, siblings, at school, and even their living situations. Where a person is located at the time of learning determines the way of expressions are used. However, they can also be learned by individual beliefs and morals.
There are different types of emotions, but the first ones that come to mind are sad, happy, scared, and angry. When it comes to sadness, this emotion is shown by many different attributes. Many will see a frown or maybe even crying. How are these actions created? For the people who cry, they most likely grew up with around people who accept tears without judgment. Others who refer to crying as "weak", they probably grew up in survival mode. Stay away from the tears or get tore down. Same thing with happiness. Some people think it is okay to always smile because of how their family judges it.
Now, being scared and angry are different. Though these are still learned emotions, they can be known a little bit differently. Anger is how a person reacts to conflict or displeasure. So, someone who displays an uncontrollable amount of anger could have learned it from their parents and family. However, some people learn anger for themselves. A person who has a very angry person in their life may choose to go the opposite direction. They may actually gain a fear to performing the actions they have observed from their close individual. Therefore, the learned behavior of anger was manipulated to prevent pain and chaos they experienced. Same goes for being scared, the negative actions displayed negative results and enabled a person to teach himself how to feel.
So, what does this mean? People are different because of their backgrounds. Emotions are clearly taught either to a person's self or by their surroundings.
