Diary Entry on Skin Color: May 17, 1977

Would somebody please interpret this journal rumination from the fourteen-year-old version of me, remembering that I was in an almost all-white high school?

It's clear that I was procrastinating my algebra by writing in my diary about an unrequited crush, but what exactly did I mean by "I wish I could hide behind my skin color more often, instead of cowering nakedly in front of it"?
