Billy's brows were still raised in a box of surprise, confusion, and interest. Billy wouldn't say he was a complete social pariah or a hermit, but it wasn't every day that people sought him out. Or, y'know, shouted his name across a crowded store surrounded by a sea of customers trying to enjoy their latte and scone. He shifted the satchel on his shoulder, and adjusted his glasses on the bridge of his nose -- of course he'd be wearing these things right now -- and tried to casually step aside and away from the self-help section to distance himself from the extreme loserdom that he could feel creeping his way.
"I suppose," he replied, "coffee can make people jittery." He paused. "Too much and it kind of..." He raised his hands to signal toward his head. "Makes me a little discombobulated." He paused. "Or makes my brain run like a mile a minute." It was...a problem. Oh, curse you tasty but inevitably treacherous caffeinated beverages.
Billy stared at Teddy's hand for a moment as he introduced himself and, after a brief moment of hesitation, took his hand and smiled. "Right," he said, "we met on Thanksgiving, right?" He offered him a small smile. "It's nice to meet you again. Teddy." He tilted his head. "I used to have this green stuffed monster named Teddy when I was five." His face flushed. "My parents said I thought Teddy bears were too mainstream." He hoped the joke was enough to deflect the random, sad overshare.
