What does Gene recall about his childhood while at Devon?

Gene recalls his days with Phineas. In particular, their first attempt to jump off the huge tree into the river. The jump is ‹a daunting and somewhat dangerous feat that is usually reserved for senior boys. Phineas, being the daredevil, goes first‹and Gene is the only one from the small party that he is able to persuade to follow him. They head back toward school, late for dinner; Phineas, the rebel of the two, exasperates Gene by making him really late, and then Gene gives in and decides to skip dinner altogether with his friend. Gene is normally a conservative, conformist type person, but under Phineas' potent influence, he becomes more devil-may-care and consents to break the rules with his friend.
