Everyone has Grumpyitus. It is a disease where when you are irritable and grouchy, you are being effected by Grumpyitus. Most symptoms include; grouchiness, irritableness, loneliness, grumpiness, and the feeling of being misunderstood. If you are experiencing Grumpyitus, the only way is to wait until you feel genuinely happy again. If it is at the expense of others, though, then you are still experiencing it's effects. Don't be frightened or scared if you experience it. It will wear off eventually.
