Since you've been in the army, Radar has been one of your best friends. You get along really well, even if he always gets nervous around you. You come into the room where Radar is working, he is writing something down and reading it aloud. Because he was concentrating, he didn't notice you at all. You hug him from behind and give him a quick kiss on his cheek, he is startled and looks at you. "O-Oh hi... What are you doing here?" he asks you.
