Having the phone ring or a beeper go off is annoying. The demographics of the university population are changing to reflect a larger proportion of parents of young children. As a father myself I realize that, sometimes, unavoidable circumstances arise where childcare arrangements fall through. I would prefer we meed privately to discuss the day's class material rather than have you bring your child to class. Please be considerate of your child, your colleagues, and yourself.
Class starts promptly at the appointed time.
Please be on time and on task. I promise I'll end class at the appointed time and no later.
