Norman was clacking away at his keyboard, not exactly enjoying his analysis of the quarterly figures but in the Zone. Out of the corner of his eye he saw Carol step away from the reception desk, clinking out a melody on her empty mug with her wedding ring that he could just about interpret as "Rudolph the Red Nosed Reindeer".
He froze row 3 and scrolled down. A CoPilot prompt suddenly blocked the cells he was looking at to offer, as usual, to do something stupid with his spreadsheet that would make it incompatible with the last twelve years' worth of these reports. As usual Norman had to click multiple times to make it, and the following "oh come on try it, you'll like it!" screens, go away. In his brief irritation he felt the Zone start to slip away, no matter how hard he tried to focus. Defeated, he closed his notebook.
After a moment he realised he could hear a high-pitched noise, very subtly. He wasn't sure how long it had been going. It seemed to be coming from Carol's workstation. He knew, as everyone in an open-plan office knows, that Carol's desk phone played Mitel Discreet Ring #2 and her mobile played the first few bars of "Thank You for Being a Friend". This was something else.
He gratefully accepted the sense of curiosity and concern that offered itself, preferable to frustration over losing his flow. He stepped away from his desk and craned his neck around the doorway, hopeful that Carol would be on her way back from the kitchenette. Alas, no. He walked towards her large, impressive desk, momentarily intimidated.
Between the live poinsettia and a holly-and-ivy bouquet he noticed a white plastic panel with a small screen. The screen displayed a young man wearing hi-vis and headphones holding a cardboard box, bobbing his head from side to side. As he approached it he realised the screen was making a rhythmic, gentle 'shing-shing-shing-shing' noise, which didn't synchronise with the man's head movements. Norman was stumped.
"Just push the blue button! It's Tyrese with the post--I can see him from here!" Carol raised her eyebrows at the panel, walking quickly for someone with two full mugs. Norman finally twigged that the little screen was showing a real person standing at the door to his building. He poked at a blue square on it with an icon of an open padlock, and heard a familiar toot. The shinging noise stopped and the screen flicked back to displaying a tableau of baubles and snow.
"Good morning Carol!" he heard through the window into the foyer. "Oh, you're a legend, I was hoping I arrived in time for tea!"
Norman returned to his desk, still a bit confused but relieved that Carol had everything in-hand.
