Cal arrived late today, began our sessions with a 14-minute trip to the bathroom and couldn't hardly pay attention when we were together. So, this was quite frustrating. I did speak briefly with his mother, who did not know that Cal had been given an assignment that was due the previous Friday. Interestingly, Cal used the excuse that he thought he was switching tutors as for why he didn't do the assignment! The good news is that his mother pledged to support me wholeheartedly.
