Which Buffy the Vampire Slayer character are آپ most like? 

You're Giles.

In your group of friends, you're known as the smart, practical one. Rarely impulsive, you tend to think things through. Before big decisions, you may even do a little research. You probably feel at home in your local library (it's hard to beat that quiet calmness), but if the shelves start shaking, keep an eye out for potential hellmouths. Your other Giles-y qualities include: helpfulness, reliability, and reluctance to express your feelings. You'd rather focus on the task at hand, and do your best to live up to your own standards -- and those of the Watchers' Council.

True-except I can be impulsive.
