A subtle buzzing noise comes from inside my head as I lay on the ground, groaning in pain. How did I get here?

Oh yeah...

Wait?

How did I get here?

All I remember is going down the hill on my bike.

My ankle shouldn't look like that, should it?

I lay back down, eyes watering and swimming with black spots.

"Someone help," I try to say, but it comes out garbled and messy.

A black cloud passes over my eyes and I slip away into it, silently.
