As teachers, we all try to establish that all important teacher/student relationship to engage students in learning and growing. Creating extra time for interaction beyond the instructional portion of the day is a great way to strengthen this relationship.
Teachers often think in terms of beginning contract time and ending contract time in terms of their day, causing them to shy away from attending outside-the-school day activities.
