Professor , I am going to need to leave class early today .   What is the problem ?   I need to go to the airport to pick up a relative .   Are you planning on having someone take notes for you ?   Yes , I've got that part covered .   When , exactly do you need to leave ?   I don't need to leave until the very end of class .   Fine , but next time try and not have to miss class again .   Thanks , Professor . See you later !
