He was a gentle man with playful, boyish delight and a knack for shooting elastics, making paper airplanes, and flipping coins with his friends. He repaired everyone's broken eyewear and replaced batteries or wristbands for broken watches. He remembered his friends with theme gifts such as key chains, pens, state quarters, and tiny flashlights. Warren knew considerable rock 'n roll history and lore. His favorite group was The Doors.
