Liam was in the laundromat, folding his laundry, when the song came on over the speakers. He stopped mid-fold, the cotton sheet drooping from his hands. It was a karaoke version, slightly off-key, but still undeniably his song. He felt a profound sense of loss, a weight settling in his shoulders. He remembered the days before the success, before the fame, when music was all that mattered. He remembered the girl who inspired it, the empty apartment, and the loneliness that spurred the creative drive. He felt the phantom pain of that loneliness again.
