On Poetry Daily, Alan Michael Parker has a devastating poem about lost children and ghosts and shame. Here's a quote: "Once when was son was young/I drove off without him..."
Once, in a Seattle Macy's mens clothing department, I lost my son. He was four. I called for him a few times, figuring he was close. But when he didn't respond, I grew increasingly panicked. A few other customers also started looking for him and then, just as an employee was going to issue the store-wide lockdown, I heard my son giggling. He'd hidden beneath one of those circular clothing racks. He thought we were playing hide-and-seek. Terrifying.
