Follow Me Blindly

Phineas, I know you're probably wondering where I am. Why this isn't my handwriting, why I didn't come back from that visit to Pinky at the vet. Why I'm writing you a letter while you live right across the street. Why you haven't seen me in three weeks. Well, the truth is, when you do, I won't be able to see YOU. I lost my sight, Phineas. Permanently.
