The comfortable space of the library began to feel constricting.

He picked at a loose thread on his jeans, staring at the floor. He wanted to say something, anything, but his tongue felt thick, trapped. He wanted to reach out, to grab her hand, to make sure this wasn't real.

The sunlight streamed through the window, highlighting dust motes dancing in the air. Time seemed to slow.
