Have you ever "gone psycho" on someone?

I have an older sister that “flips out” all the time… she once threw an entire pizza at my other sister because they were arguing over… God knows what. (this was as an adult, not a teenage thing.. I won’t even BEGIN to tell you about broken doors, windows, mirrors, black eyes, etc, from her teenage years)

Yesterday morning, after a fight with my husband that spilled over from Saturday night, I chucked an entire Jewish Apple cake that I baked for him into the trash… ok, so maybe not completely PSYCHO… but it’s about the most deranged thing I’ve done as an adult in an argument. I felt quite out of control… and it was scary to me.

Do you ever get out of control in an argument? Have you ever just totally flipped out and gone psycho? What happened? Do you think that it’s ‘normal’ to happen every once in a while?
