There was no way he could have known his Uncle Ben would die, but that doesn't keep Peter from beating himself up. He leaves Uncle Ben (who could cook a mean pot of rice back in the day), and walks, unaided by his spidey powers, into the setting moonlight. His head hangs low as he considers that his special abilities make him more responsible than others. He bears such a heavy load on his shoulders, not because he wants it, but because it has been thrust upon him.
As we work our ways through life on Planet Earth, we must also pick up responsibilities here and there. These roles appear when we advance through learning situations, graduate through new levels in our jobs, and develop new abilities and interests. If we fail to acknowledge them, we will fail in our field of study. If we try to ignore them, we will be exposed as frauds. If we fail to pick them up, we will be forever incomplete.
My hope is for my students to find and uphold their responsibilities now and throughout their lives. Not because I pointed them out, but because they have searched for how to help others and improve themselves.
