"Mmm?" his eyebrows quirked up when she said it had been a good day. He was glad of that, and as she went on to describe what was the root of her discontent, he said a silent thank you that she wasn't upset with him. He chuckled at her suggestion. "Y'know, lass, if the thought - and the potion - weren't so repulsive, I think you'd probably have a fair number of people itchin' t'try."
He shrugged slightly. "My day was alright. I seem t'have more classes on Wednesdays than almost any other day...and windin' up with DADA is not high on my list of favorite things, but..." he smiled at her, "...it's taken a turn for the better in the last five minutes." He leaned back in and pressed a kiss against her temple. Taking a chance that she wouldn't hex him for appearing to forget it, he murmured "happy birthday, love."
