"What is going on here?" A voice by the door asked in a surprised tone. His friend continued to walk further inside his office without waiting for permission. "Are you ok, man?"
A sudden movement by the door snapped him out of his trance, finding his friend looking at him with confusion. He quickly took a deep breath and turned away from him, walking back to his desk, ignoring his friend's question completely.
He saw in his peripheral vision that his friend followed him, sitting in front of him comfortably like he never needed an invitation. On other occasions, maybe, but not today.
"What are you doing here, Mike?" He finally asked, shifting his face until his eyes met his friend. "I did not call for you." He was dismissing his presence, so his friend should heed the warning in his tone and leave.
