My heart sank as I opened the front door to see Vince bouncing up and down outside like an overexcited puppy. Cheery, creepy, geeky Vince. Six and a half feet of him, and every inch annoying. M“Hi, Steve,” he said, flashing me a buck-toothed grin, twitching to get inside. “Hey,” I responded, masking my lack of enthusiasm. I opened the door wider to let him through. “Wait till you hear about my new app. It"s brilliant!” He waved his phone in my face as he passed. I rolled my eyes as I closed the front door and trudged into the living room after him. He was always doing this – coming around to show me the latest game he’d devised, or app he’d written, or gadget he’d built. Each one worse than the one before. “Gonna be a millionaire,” he was saying as he dropped onto the sofa uninvited.
