Liam saw it on Twitter, a trending hashtag: #MyHighSchoolSecrets. A chill went down his spine. His high school diary had been nothing if not a chronicle of awkwardness. He clicked the link, his fingers feeling clumsy on the keyboard.

The website was a cheap imitation of a digital scrapbook, filled with poorly scanned images and painfully honest prose. He cringed at the overly dramatic language, the incessant self-pity. He leaned back in his chair, a wry smile slowly forming on his face.

He found himself chuckling at his youthful audacity, the sheer drama of everyday life. He felt the weight of the past lift. He felt strangely free. He closed his eyes and breathed deeply, a feeling of lightness he hadn't known in decades.
