Basketball with Jay

Who am I? That's a really hard question to answer. Who do I think I am? Easier. I think I'm Skyelar Slivers. And I think I'm pretty average. Other than the fact that I've got a good sense of time, am athletic, and have no friends. Okay, well that's not true. I have one friend, Blue jay. I've known Blue jay since practically forever. He's always been there for me. Everyone thinks that he's just an imaginary friend. But he's not. He's real. So am I. Who Am I? I couldn't tell you.
