Temper Tantrum!!

Wow... has your child ever had a super-sized, enormous, huge-ass temper tantrum that lasted for an hour or more?
My 5 year old has the occasional tantrum, much like the one I described above. Hers are super cell tantrums, much like that of a tornado. She starts off starting to jump up and down, then her face gets red. Her eyes get all glazed over and red, mind you, there are NO TEARS.... her tantrums are all about CONTROL and the rage that follows if she doesn't get her way!!
Most often the things that set her off are VERY minor little nothings to any passer by. This time it was the fact that her sister, age 3, joined the conversation without being invited. She merely said ONE WORD and that was the ignition to the tantrum. My 5 year went full force into an F-5 raging tantrum that lasted 40 minutes!
When she is mid-tantrum, there is NOTHING that can be done to ease the rage. She generally says one thing over and over and over and over again. This time it was, "I want to tell you something!" to which I replied, "Yes? What do you need to tell me?"
And rather than just tell me, she kept repeating, with more and more rage, "I want to tell you something!" There was nothing that could be done. She was out of control, out in the middle of the back yard where the WHOLE neighborhood could hear her yelling and see her flailing herself on the grass, kicking and screaming. My 3 year old stared at her in disbelief and my husband simply went inside!
I stood on the patio, waiting for the storm to clear for what seemed to be forever. She kept up with fierce tempo, "I want to tell you something!""I want to tell you something!""I want to tell you something!" Screamed over and over again in an eerie rhythm. It was almost like she was in a self-induced trance or something.
After being ignored for about 35 minutes she showed signs of recovery. She had demands though and was determined to show the world that this calming of the storm was HER CONTROL and hers only. She made demands that I STAY STANDING right where I was until SHE told me otherwise. I found that amusing and started to giggle which only fueled the storm back to an F-4 for a few moments until she realized that I wasn't going to cave to her demands. She gathered her senses, stood up and walked over to me, asking for a hug.
I guess they get all their frustrations bottled up to a point of explosion and when that ignition is sparked, it just goes full force until the needle is on empty!!!
Thankfully those tantrums are Few and far between!!
