I wish I could throw a fit!

As a child it is so much easier to get what you want. You throw a tantrum and if all goes well the adult will get tired of shushing you and giving you time outs and hand you your heart's desire. As an adult it is much difficult to get what you want especially if its something you cannot/aren't supposed to have. What do you do then to quench your heart's desire?

Oh lawd give me strength :)
