The triggers of laughter
People laugh for various reasons, either because of positive or negative causes. However, according to online dictionary sources, the definition of laughter is: “to express mirth, pleasure, derision, or nervousness with an audible, vocal expulsion of air from the lungs that can range from a loud burst of sound to a series of quiet chuckles and is usually accompanied by characteristic facial and bodily movements.” Also, people have different responses towards different causes. For example, giggles and chuckles happen when the cause is slightly humorous; grins and smiles are often associated with sentimental situations; guffaws and howls trigger when watching a hilarious movie or TV drama. Nevertheless, the definition of any form of laughter can still vary by people.
Humor is the most common factor of why people laugh. Yet, every human being has their own definition for humor. Sometimes, one thing that is funny to you does not necessarily mean it is funny to another person. It is due to the different past life experiences that each individual has been through. Whenever people feel the connection between themselves and the topic, people laugh.
In some other cases, a smile may symbolize happiness or shyness. A smile can be identified mostly in couples where, a slight curve appears on a girl’s face with blood-red blushing on both cheeks. This is a universal sign of being in love. This category of laugh is mild and gentle, which is regularly found quiet, unlike those loud hysterical laughs with a “haha” sound.
Furthermore, people laugh because of embarrassment and awkwardness as well. Laughter often takes place in some uncomfortable situations. Such as, party or social occasions, where people first meet. Those uneasy surroundings often put people in a situation of not knowing how to respond; therefore the best solution is always smiling. It is not like smiling or laughing could break the condensed atmosphere, but it is a spontaneous reaction to these kinds of situations. Also, smiles give people a comfortable and welcomed feeling, even without any words.
Smile is a natural and god-given gift to all human beings. Imagine a world without any laughter and smiles. No more curves would show upon the lips; no more warm welcome from a friendly household. How terrifying it would be if this world was created without such thing called laughter. Even though people do not always laugh for positive reasons, regardless of the reason hidden behind, a smile does always look pleasant and optimistic.
