Aww... she looks like a very beautiful girl, McKinsey!

As for her temper... just give her some time to settle in, see how she does. It's possible she's just completely pissed about having been shipped in a little box, lol.

All the best ones have a little fire in them

EDIT: Just another note... she looks a little dark. Boas tend to go through color phases depending on their temps. She's probably a little cold, too.
