id say when i had changed high schools, from a charter to a public. the charter had a different grading system for the transcripts and thus i had to work and take more classes in two school years at the public school to pass on time(usually its 5-6 periods but i took 8 periods for both years). i'd day i earned more responsibility and a bunch of new knowledge.
Nothing huge has ever really happened to me, but I fell down a hill once. Yeah, it hurt a lot more than it sounds and it made more careful and worried about hills .~.
