Well, she has been sighted ~Edited, technically speaking it's advertising~ I thought you might want to know....^.^
I think it might be, considering she may well be a 20-year old übernerd who has been pulling our collective legs all this time. Either way, she could have picked it up in a lot of places and thought it'd be funny. But yeah, it could be someone else pretending. Guess we can't tell at this point.
Sadly no, I know the middle school she goes to and I have friends that go there. I think I saw here at the local ice rink as well. I hope it wasn't her because I almost knocked that person over by accident. >_>
