Wahoo! I'm special!



OK, now it's my turn...

I'm not ahead; I'm not behind
The middle's where I be.
And despite which way my head is turned
The former two I see.

I have a dark side to me,
e'en though daytime is my friend
The actions I do now
might not hit 'till the end.

Who am I? As it seems
that's up to you to guess
But who I really am
I know better than the rest.

Good luck!
