hello walter. i'm sorry to interrupt. walter, shelley can't make it down to the nyu conference to present your paper. i'm going to need you to cover for her. she's been put on bed rest until she has the baby. next week. we'll cover your class and make the arrangements. i understand but you co-authored the paper and the dean wants it presented. he wants to keep shelley on track for tenure. you're only teaching one class, walter. i'm sorry but there really isn't another option at this point. that may be the case but you are the co-author and she can't go. look walter, you can take it up with the dean if you want, but, as your friend, i wouldn't advise it. not with that argument. good bye.
