with Egotists. Most likely from some past experience. Then again in youth the extrovert hasn't the experience. They can easily fall into egoism and from there to the egotistical. The introvert in the other hand with too much such experience may fall into cynicism.
I'm paraphrasing someone's book that's only virtue was it made a great eyeshade when it bored me into a siesta. I learned never to butt heads with the extroverted or frighten the introverted.
Somewhere at some time the lion turns coward and the mouse roars.
People never really fit in the neat categories we might wish
to place them.
Happy Valentines Day.
