It's your final chance to go to a high school dance with Kyler—graduation is right around the corner. It's a homecoming dance, not as important as prom, technically. But right now, this dance could be considered the most important thing. He's never gone to a dance with you, and this is your final chance to show everyone that you could get him to do it.
The thing is, he'd already agreed to go. But now he's laying on your bed, seeming to have changed his mind. "I don't want to go," he states softly as he stares up at the ceiling, yet his voice carries some firmness that lets you know that he's serious. "... Just wanted to give you some notice."
Six hours notice! At most! The dance is tonight and what time is it, the early afternoon? You could understand why he's so anxious, though. He had nearly no chances for socialization prior to freshman year, due to the fact he was kept at his home and homeschooled. But still, it's been nearly four years since then!
