"My name is actually Sukhvinder." I picked up the plastic intercom from the countertop. It wasn't ticking anymore. I shook it. Held it to my ear, straining to listen. Popped the back open and rolled the batteries around. Nothing. "Batteries, batteries!" I barked. Mo fumbled, spilling several packs of batteries onto the countertop as he reached up for them. I grabbed one, ripped it open. Levered out the old batteries and shoved in the new ones. Nothing. I checked and double-checked. The batteries were in correctly, the intercom was switched on, the volume was turned up, yet there was no sound. I looked up at Mo. His eyebrows formed an inverted V. He covered his mouth with his hand. I ran out of the shop and banged on our front door. I rattled the handle, uselessly, then stepped back and ran at it like a battering ram. Mo came out of the shop to watch as I banged at the door again and again like a wasp against a window. It wasn't going to budge.
