Kwame · postgraduate student from Kumasi · advanced
At his department's welcome party, Kwame walked up to two lecturers who were talking quietly, face to face. He said hello. They smiled politely, gave short answers and returned to their conversation. He felt terrible.
Later, a friend explained: “They were closed. Look for the groups standing in a horseshoe, with a gap. That's an open door.” Kwame found a group of four laughing near the window, with a space at one side. He stood in the gap, listened for a minute, then laughed at a joke and added a comment.
Within five minutes he was part of the group. Same Kwame, different door.
