Roses
"Roses are red, violets are blue, sugar is sweet, and this drabble's for you." Ianto looked down at the small, singing robot at his feet. It wasn't a great piece of technology. For one thing, it couldn't hold a tune.
"What?" he said, bemused. The lights on the robot's metal casing flickered. Ianto guessed that it was some form of alien technology, although he'd never seen it before. The lights flickered green and it had obviously found the program it had been looking for.
"Blame him," it said. Ianto looked up.
"I'm sick of these drabbles, aren't you?" Jack said.
