When referring to a person's personality and attitude, most definitions of emo hold that an "emo person" is candid about their emotions, sensitive, shy, introverted, broken-hearted, glum, and often quiet.[6][9] Emo personality is also often connected with writing poetry, which addresses confusion, depression, loneliness, and anger, all resulting from the world's inability to understand the author. Emo poetry uses a combination of any of: a highly emotional tone, stream of consciousness writing, a simple (ABAB) or nonexistent rhyme scheme, references to the flesh, especially the heart, heavy use of dark or depressing adjectives, concern over the mutability of time and/or love, and disregard for punctuation, grammar, and/or spelling. Themes such as life is pain are common.[10]
