Fear's Got Your Back!

The enemy of courage,
The best friend of heights;
I am fear.
I hide away
During the brightest of times.
The light,
it burns.
I strike in the dark,
Like the owl;
Whose head spins all the way around.
Happiness hardly takes me;
I am fear.
Beat me,
I always come back,
In one way or another.
Give in to me,
Give in to me,
I dare you.
I am fear.
I'll be your best friend.
