I'm going to leave class early
Why are you leaving class early?
I want to visit my family and friends
You have a responsibility to be in class and be a good student. You should meet with your friends and family after class is done or you could get a bad grade due to missing important class material.
Come on! I want to goof off sometimes.
I think your family wants you to do well with your studies. How about you make a plan to hang out when you don't have anything else going on? I think that would be a healthy balance.
