You want the truth? well here it is.
eventually you forget it all. first you forget everythink you learned- the dates of wars and pythagorean theorem. you especially forget everything you didn't learn, but just memorized the night before.
you forget the names of all but one or two of your favourite teachers, and eventually you forget those, too. you forget your junior year class shedule and where you used to sit and where your bestfriend's phone number and the lyrics to that song you muste have played a million times. and eventually, but slowly, you forget your humiliations- even the ones that seemed endelible, just fade away. you forget who was cool and who was not, who was smart, pretty, athletic, and not. who went to a good college. who threw the best parties. who had the most friends. you forget all of them. even the ones you said you loved, and the ones you actually did. they're the last to go. and then once you forgotton enough, you love someone else. :)
