How to Turn Your VC into Your Worst Enemy?

VC's have been my best friends and my worst enemies, in ways that are not always within my immediate control. In the process, ironically, I have come to respect Venture Capitalist as a profession, which I believe is the least understood if not the most misunderstood. And I am convinced that mistakes I have made with VC's (eventually turning them into my worst enemies) were a result of my inexperience as a CEO compounded by a total lack of understanding of who VC's are and what they do for a living.
