Girls why do you get quiet around a guy?

Anonymous
A girl at my work seems to be able to converse with everyone at work, including my friends but as soon as I enter a conversation she completely goes quiet and starts looking around the room or her phone or anything else really. I've caught her steal glances a few times during all this but doesn't say anything and as soon as I leave the group she goes back to being talkative / involved in the conversation.

Any input?
