"Wow, you surprised me! I didn't even see you there, and I'm pretty sure I would have noticed someone approaching. Now I feel a bit flustered, to be honest - it's not every day I get caught off guard like that. But I guess the surprise is out now! Anyway, enough about that. How have you been? I feel like we've lost touch, and I'd love to hear all about what's been going on in your life."
