Writings In 2005, Aberlin contributed the essay "The Blonding of America" to the literary web site Fresh Yarn . In the essay, she comments on privilege and physical appearance. The point of departure for her reflection is the purchase of a blonde wig to hide her first gray hairs. Wearing the wig, Aberlin is aware of how it erases racial or ethnic features and how her new look evokes a more glamorous feminine stereotype. She observes how this change to her appearance effects a change of consciousness: "I put [the wig] on, and I don't even notice the homeless anymore." She concludes the essay: "Later on that evening, I saw a yellow school bus, filled with Chasidim. On the sooty back window of the bus, someone had drawn a swastika. I'll tell you...it certainly feels a little safer....being blonde."
