the state in which you both have nothing to do, and you are not tired. These statuses are always present, such as during the day. During the day, if you have nothing to do, and its during the day, so you arent tired, you are bored. Also, when you are just talking to friends, waiting to get tired. thats boredom too.
Me: God, im bored. theres nothing to do, and im not tired, so i cant sleep
Friend: get some sleeping pills, that will cure your boredom
