He was about to ask her if she normally dressed up, his thoughts straying to formal wear and then since they were dressed up they could have someplace to go, and since they had instruments maybe they could perform for others, but at some kind of private venue... and then he got an idea. Not that he would get up and play the few chords he knew in front of people because he didn't consider himself good enough, but if Sam had studied the clarinet for longer, she was likely really good at it.
"You could perform at Luminescent one night," he suggested, excitement leaking into his voice. "It's very low key. We play canned music at a low volume usually but there's a space for a musician to sit and the room is designed for the acoustics to travel out from that point to everywhere else in the room."
He stopped talking when he realised that his enthusiasm might not be shared, but it felt like a very Sam thing to do when he was saying it because she was often full of surprises with the things she did and knew.
