The Windmills of my Mind

What is “emotional instability”?
what does it mean to be “normal”?
What are mood swings? is it safe to say that any one can experience this? And why is it that some experience sever ones?
why do children have tantrums? even if they get their way..
Do adults throw tantrums? Is that what we call drama?
what is being “bi-polar”, and are we all a little bi? yet some more so?
is being overly sensitive to one’s self, a good or bad thing?
