He couldn’t wait to show him the demo. He needed his approval, his guidance. He burst through the door, ready to speak a mile a minute. The space was empty. The computer was gone. The coffee machine was gone. A yellow sticky note lay on the desk. “Off to the beach. Best of luck, Martin!” He felt a strange flutter in his stomach, not entirely unpleasant, but undeniably disorienting.
