First, I'd wonder if I was still dreaming.
I'd probably spend the first hour trying to determine if I was insane, once I'd figured out that I wasn't dreaming.
Then I'd probably be really excited.
I'd get the hang of having a super long tail (which I'd be extremely excited about!). Then I'd probably stare at myself in the mirror for a while until I felt pretty used to how I looked. Then I'd go out and see if I could tell my friends about it without them freaking out.
' And then I'd probably tell my sister. And maybe the rest of my family, if they could handle it.
And then I'd just be super happy.
