no periods, only commas

yAy AmY. on tuesday my sister received her masters in social work from nyu. at lincoln center. as the rolling stones played outside on the plaza. only in new york city.
it was a full day. full of events, full of plans, full of waiting, full of speeches, full of emotion, full of thought, full of inspiration, full of cameras, full of taxi rides and getting here & there, full of watch checks, full of blisters, full of pride, full of joy, full of missing people, like my dad, who are no longer with us but we wish had been there . . .
the speaker at the commencement touched quite candidly and engagingly on the need for social change resulting from our lack of a politicized society and the importance of changing the system to rid it of flaws rather than changing the individual to fit in a flawed system. i've always shared much of my sister's idealism and her drive to elicit change, no matter how big or small, and i've always supported her on the decision to use social work as her medium to achieve that end. her graduation reinforced all of that for me and made me believe in it, and her, even more. which i didn't think was possible. i am so proud of her and all the good she has done already, and i know an infinite amount lays ahead. the world is a better place because of her.
it's funny how unlike an ending her graduation seemed though . . . maybe because this program was 2 years and not 4 and so the end snuck up on me, catching me unprepared? or maybe because an undergraduate degree seems like the end of that long road of formal education we embark on as toddlers, really, when you consider the years spent in nursery school that lead directly into kindergarden, and, so, when that moment arrived for each of us it felt like, 'finally, we have finished, we can take a deep breath now and do whatever we want to do from now on!' (a big hahaha to the naivete of that thought, but, anyway) this masters degree, on the other hand, really is a stepping stone, a transition, a beginning for her, her career, her aspirations. this is not the end of something for amy, not a period, just a comma
