Severus really was just practicing dancing, he had not intended to get so close to Lily that he was just a breath away from kissing her. He worried his bottom lip looking at her lips, he knew he would be in a world of trouble if he gave into the urge and actually kiss her. Oh, he wanted to kiss her but, even though the dancing was nice and it really seemed like Lily wanted to go to a ball with him, he knew he should not indulge in a fantasy like that.
"I am not so sure I would be a good dancer." He spoke trying to break the tension between them, he would never do anything that would destroy their friendship or at least he would never do it on purpose. "But I am sure girls rather listen to Binns lecture then go to a ball with me." He grinned trying to make the last bit sound like a joke instead of his real insecurities put into words.
