Samantha and Ira bumped into each other on the sidewalk. Ira apologized. "No, no, I apologize," said Samantha. Ira said, "Believe me, it's not your fault. I'm always bumping into things or people. I'm blind." Samantha said, "You're blind?! Guess what? I'm blind too. I've never bumped into a blind person before. How long have you been blind?" Ira said, "I lost my sight last year. I had a skateboarding accident." Samantha said, "I'm sorry to hear that. How old are you?" Ira said he was 15. Samantha said she was 16. She said she was born blind. Ira said, "You were born blind? Then you've never seen anything. You've never seen yourself. You've never seen the sky. But you know what? You're lucky. You don't know what you're missing." Samantha said, "No, you're the lucky one. You at least have seen people and things. You have those wonderful memories."
