Lemma 1a: prove that i am done with classes for the rest of summer.
PF: assume by way of contradiction that i am not done with classes for the summer
this implies that i have to go to class on monday
given that i would go to class on monday if i had class on monday
and also given that i am not going to any classes on monday or any weekday thereafter
one can conclude that there is no class on monday
therefore there is a contradiction because if there is no class on monday or any other weekday thereafter during the summer
then i must be done with classes for the summer and i kicked all of their asses!!!
