Embarrassment or awkwardness is an emotional state that is associated with mild to severe levels of discomfort, and which is usually experienced when someone commits a socially unacceptable or frowned-upon act that is witnessed by or revealed to others. Frequently grouped with shame and guilt, embarrassment is considered a "self-conscious emotion", and it can have a profoundly negative impact on a person's thoughts or behavior.

Shyness is the feeling of apprehension, lack of comfort, or awkwardness especially when a person is around other people. This commonly occurs in new situations or with unfamiliar people; a shy person may simply opt to avoid these situations. Although shyness can be a characteristic of people who have low self-esteem, the primary defining characteristic of shyness is a fear of what other people will think of a person's behavior. This fear of negative reactions such as being mocked, humiliated or patronized, criticized or rejected can cause a shy person to retreat. Stronger forms of shyness can be referred to as social anxiety or social phobia.
