during my junior or senior year - i can't recall which - i somehow managed to juggle my schedule such that i was done with classes by 1pm. i was the only one who did this (it required the questionable decision to take biology over the summer), and consequently, i had one to two free hours between the end of my school day and the end of my friends'. my only recollection of how i filled this time was screwing around in novel ways.
like crashing one of berkeley high's latin classes.
