The edges of his lips turned up as he felt her take his hand, and he ran his thumb over her knuckles. "So...how would you tune a fish, if you could?"

"Er... I'm not sure. I... I don't think you can?"
She continued to smile.

"Okay, but like, if it was possible would it have pegs sticking out of it? Kinda like a guitar?"

"Probably? Or maybe they would have strings?"

"Maybe. It's very possible," he agreed.

She nodded, then there was silence... 'Uh...What other subject... is there to talk about?....' She asked herself. She felt a little warmer, she was starting to get a nervous, but she still held his hand as they were walking to class

He didn't notice her getting nervous. If he had, he would've stopped and asked what was wrong. Instead, he kept going to class

They made it to class. As they got to the door she let go of his hand and sat down in her seat.
'I... wish I could say something...' She thought to herself

Shawn hadn't minded the silence, because not all silence had to be an awkward silence, you know? Besides, what would you even say after talking about how you would tune a fish if it were possible? He took his seat next to Brook

Right... but Brook kinda felt awkward, any silence to her is... well uncomfortable.
She picked up her bag and put it in her lap, looking for her supplies.
