Is there a type of person that intimidates you?

I like to think of myself as not being easily intimidated; I am not intimidated by most men, or by doctors, Phd’s, or most other job titles, etc. But for some reason my lawyer really intimidates me. I have no idea why, he is younger than I am, weighs a buck fifty soaking wet, is an arrogant jerk (exactly the kind of lawyer I wanted representing me), and has never been anything but professionally polite to me, but for some reason he intimidates the heck out of me.

Is there a specific type of person you find intimidating? Are there those who intimidate you for reasons you can’t quite put your finger on?
