We are sometimes dragged into a pit of unhappiness by someone else’s opinion that we do not look happy.

Some people wish they were as happy as or happy like some people think they are.

The presence of someone we are angry at often makes us suppress or fake a smile or a laugh.

The smiles of the unhappiest are often the widest.

Even suicidal people can smile.

Genuine happiness is not nearly as common as a fake smile.

Unless they are off duty, no matter how wide it is, and even when it is sincere, a smile seems fake if the job description of the person who is smiling includes smiling.

Beauty is instantly more than doubled—ugliness, more than halved—by the mere act of smiling.
