Obi-Wan could tell that Peter felt a great deal of pride (he didn't even need the Force for that), so he just smiled and let the man think he did it on his own. No point in explaining his true identity just yet, right?
"Obi-Wan Kenobi." He simply reached for the man's hand and shook. "It's good to meet you Peter. And um..yes. It was actually a surprise. My systems shut down and I had to do my best landing...here. Where is here by the way?"
Peter was still confused. This planet hadn't been on his scanners just moments before. He looked around then back at the man. "I assume you're a local?"
