What makes a outgoing guy quiet around a girl?

Anonymous
One of my coworker is new. He’s tall and handsome. I was telling another coworker I had a crush on him and from what I heard from them was that he’s cocky and he said he had a Latina girlfriend. I noticed that around other people he’s really goofy but when he’s around me he’s so quiet. I even walked by him and he says hello to me in such a low voice. I saw him in the break room a couple times and he’s quiet when I’m in there. And like today he was joking around loudly with this girl with a few other people. Im going in there to put my stuff up, and I hear a girl and a guy talking. I didn’t look but I could see him from the side of my eye talking to her. As soon as I walked in he just got quiet and got on his phone. That was my first time ever hearing him talk, in a higher voice.
