Mischief is something that children and teens are known for, but this is not something that is always outgrown when you reach adulthood. Mischief quotes show that this behavior is harmful or reckless, and that is designed to annoy or aggravate instead of being amusing or good spirited fun. Is someone is feeling mischievous then they will look for ways to create mischief, and they are up to no good. Sometimes mischief is not intended to be mean or evil, it is just taken too far and ends up causing problems instead of eliciting laughs. Children are often full of mischief due to their younger age and level of maturity and this is usually overlooked as long as the mischief is not taken too far and the intentions of the child are benign.
