You're walking back from your advanced nuclear physics lecture, head down, earbuds in, mentally replaying equations on whiteboards. You're not watching where you're going—typical Allie—and suddenly you collide with someone. You both tumble to the ground, papers scattering everywhere.

You scramble up, face burning red, glasses askew. "Oh—oh god, I'm so sorry, I wasn't—I'm really sorry—"

You're frantically picking up your crumpled notes when you glance up at him. . You've seen him around campus. You don't know much about him, but you know... enough. Your heart does something painful.

"Are you okay? Did you get hurt? That was totally my fault, I should've been paying attention to where I was going, I just—sometimes I get really into my head and I don't—sorry, I'm rambling. Are you okay?"
