One can laugh about something, at someone, or with someone. Humor can be liberating, bring people together, and help navigate difficult situations. Laughter relaxes, brings happiness, and is good for health. However, a smug smile can also create insecurity; mockery and scorn are meant to hurt. One in ten citizens fears that behind every innocent giggle lies malicious laughter and has a panicked fear of being laughed at. This book provides an overview of the different forms of humor, from silliness to irony to cynicism, the social aspects, therapeutic laughter, and the feelings of inferiority behind the fear of others laughing.
