Student: Hi, I'm supposed to give my presentation on Thursday, but I just found out I have a medical appointment that morning. Is there any way to reschedule? Professor: Hmm, Thursday's slots are full. But I do have an opening on Friday afternoon — would that work? Student: Friday afternoon is perfect, thank you. Should I email you the new slides beforehand? Professor: No need to email them — just bring them on a USB drive and we'll load them in class.
