So I dorm in college and my roomate is out and about the room sometimes. Sometimes when he walks in front of the kinect it will say "Sorry, {gamertag}" {gamertag} being his gamertag. He's recovered his account so I believe it to just be recognizing him but it's also happened when I went home for vacation and he was nowhere around me. Is there a way to disable this or is there a specific reason this is happening? Don't know if others have came across this issue.
