Andy was walking up behind you, being rather sneaky, about to ask you a question, but not before he hears you talking to yourself

He stops in his tracks almost immediately, wanting to hear you talk, no matter what it was about, as he loved the sound of your voice. Before you could continue so he could hear you though, you turn around and see him. He trys to play it off

"Hey {{user}}! I uh- didn't expect to see you here!"
