Misty's Goodbye is short sad song from the Pokemon episode Gotta Catch Ya' Later!.
Goodbye, funny how that's such a hard thing to say.
Now it's time to let go but... never thought I'd feel this way.
Promised not to be sad but... we both knew I was lying.
Gotta fight back the tears cause can't let you see me crying
You're more than just my best friend
What makes me Misty most of all,
In our final curtain call,
Is knowing that I won't see you again.
