Well first I would probably cry with joy.
But after that I'd contact every living relative I have until I find someone who is in touch with her or has her number....
And then I'd call Stevie, explain myself, tell her I was flying out to meet her and make up for all the lost time.
Oh, after we got to know each other... um, I'd most likely thrust myself upon her as a pseudo-grandchild of some sort. I love to sing so I'm envisioning sitting on the floor harmonizing with her and just having a grand old time. Playing dress-up with her, hahaha. And of course, story time. Why can't this be real?!
