Elusive.
Cunning.  
Effected by nothing
and sparked by no one.
Spontaneous,
yet constant.
It may hide when you want it,
appear when you do not.
It comes with haste,
or slows its pace.
A child mischievous,
rebellious,
innocent, oblivious.
To force the hand of change,
like paper tossed to air...
A direct path it does not take.
