Let me tell you what happened to my homework .   OK , go ahead--what is the excuse THIS time ?   Actually , I did it , but then it got lost .   Could you have gotten it done at another time ?   Yes , I could .   You have never missed an assignment before--when will you be making this one up ?   I'll make it up early next week .   That would work , but don't let it happen again .   I'll try .
